Devaughn is 14 years older than Sydney. The sum of their ages is 110. What is Sydney's age?
Answers
d+s = 76
• substitution;
(s-14)+s = 76
2s-14= 76
2s = 90
s = 45 years old for Sydney
d = s-14 = 31 years old for Devaughn
hope this helps
Answer:
The answer would be 48
Sydney is 48
Devaughn is 62
48 + 62 = 110
Okays so you start by doing the equation 110 - 14 = 96
then dividing 96 by 2 (96 ÷ 2) which is 48
add 14 to 48 and you will get 62. We can automatically assume that sydney is 48 because when you add 48 to 62, you will get 110. I hope that this helps! ^‿^

The banana bread card states it serves 10 people. How much flour is required to make enough bread for 30 people?
Answers
========================================================
The card says we need 1 & 1/2 cups of flour
Let's convert this to decimal form
1 & 1/2 = 1 + 1/2
1 & 1/2 = 1 + 0.5
1 & 1/2 = 1.5
The mixed number 1 & 1/2 is equivalent to the decimal number 1.5
Now multiply this by 3. This is because the recipe originally serves 10 people, but we want to serve 3 times as many people (3*10 = 30 total).
So, 3*1.5 = 4.5
Now convert back to a mixed number
4.5 = 4 + 0.5
4.5 = 4 + 1/2
4.5 = 4 & 1/2
We'll need 4 & 1/2 cups of flour.
----------------------
Here's another way to approach the problem
Multiply 3 by 1 & 1/2 to get
3*(1 & 1/2) = 3*(1 + 1/2)
3*(1 & 1/2) = 3*1 + 3*1/2
3*(1 & 1/2) = 3 + 3/2
3*(1 & 1/2) = 3 + (2+1)/2
3*(1 & 1/2) = 3 + 2/2 + 1/2
3*(1 & 1/2) = 3+1 + 1/2
3*(1 & 1/2) = 4 + 1/2
3*(1 & 1/2) = 4 & 1/2
You can do this by turning the 1 and 1/2 cups into a decimal: 1.5
Then you multiply 1.5 by 3 which gives you 4.5
4.5 also means 4 and 1/2

what is the measure of 6?
explain why please
please anwser this asap.
Answers
Statement Reason
1. 3x + 7 = ∠2 (Vertically opposite angles)2. ∠2 = ∠5 (Corresponging angles)3. ∠5 = ∠6 (Vertically opposite angles)⇒ ∠2 = ∠5 = ∠6 = 3x + 7
Looking at the picture, we can see that ∠6 and 4x + 5 are a linear pair.
Finding the value of x:
⇒ ∠6 + 4x + 5 = 180
⇒ 3x + 7 + 4x + 5 = 180
⇒ 7x + 12 = 180
⇒ 7x = 180 - 12
⇒ 7x = 168
⇒ 7x/7 = 168/7
⇒ x = 168/7 = 24
Now, substitute the value of x into the expression "3x + 7" to find ∠6.
Finding the measure of ∠6:
⇒ ∠6 = 3x + 7
⇒ ∠6 = 3(24) + 7
⇒ ∠6 = 72 + 7
⇒ ∠6 = 79°

Dominic goes jogging every morning. If m represents the number of miles he jogs each day, which expression represents the total number of miles he jogs in a week?
7 m

StartFraction 7 over m EndFraction
Answers
Answer:
The expression which represents the total number of miles he jogs in a week is 7 m ⇒ A
Step-by-step explanation:
Let us solve the question
∵ Dominic goes jogging every morning
∵ m represents the number of miles he jogs each day
→ That means he jogs m miles every day
∵ There are 7 days in a week
→ That means he jogs m miles every day for 7 days
∵ m + m + m + m + m + m + m = 7 × m
∴ He jogs in 1 week 7 × m miles
∴ He jogs 7 m miles in a week
The expression which represents the total number of miles he jogs in a week is 7 m

6x - 10y = 20 in slope intercept form
Answers
A: Y= 3/5x + 2
Move 6x to the other side of the equation by subtracting both sides by 6x.
You’ll then have -10y=-6x+20.
Simplify by dividing -10 on both sides. -6x divided by -10 is 3/5x, and 20 divided by 10 is 2.
The general equation of a straight line in slope-intercept form is given as:
y = mx + c
The slope-intercept form of 6x - 10y = 20 is y = (3/5)x - 2.
What is equation of a line?The equation of a line is a form of representing the set of points, which form a line in a coordinate system.
The general equation of a straight line is given as:
y = mx + c,
where m = slope of the line and c = y-intercept.
We have,
6x - 10y = 20 _____(1)
The slope intercept form is y= mx + c
So,
Subtract -6x on both sides.
6x - 10y - 6x = 20 - 6x
-10y = 20 - 6x
Divide both sides by -10.
y = 20/-10 + 6x/10
y = -2 + 3x/5
y = (3/5)x - 2
Thus,
The slope-intercept form of 6x - 10y = 20 is y = (3/5)x - 2.

Answers
Answer:
A)Percentile for Lynette, the student who is 65 in. tall is 36th
B) Asher is 22 inches tall.
Step-by-step explanation:
Percentile : It is a measure used in statistics indicating the value below which a given percentage of observations in a group of observations falls
A) Find the Percentile for Lynette, the student who is 65 in. tall.
No. of students below 65 inch =9
So, Percentage of data below 65 inch =[tex]\frac{9}{25} \times 100 = 36 \%[/tex]
So, Percentile for Lynette, the student who is 65 in. tall is 36th
B)Ashers height is at the 88th percentile of the distribution. Interpret this value in context. How tall is Asher
[tex]88=\frac{x}{25} \times 100 \\\frac{2200}{100}=x[/tex]
22=x
So, No. of students below or st 88th percentile = 22
So, Asher is 22 inches tall.

Ana angle measure 79.8 degrees less than the measure of it’s complementary angle what is the measure of each angle
Answers
Answer:
x = 129.8 degrees, y = 50.2 degrees, x + y = 180
Step-by-step explanation:
Let's say you have 2 supplementary angles, x and y
So x + y = 180
if x is 79.8 degrees less than the measure of a supplementary angle, then x = y - 79.8
Putting this into our x + y = 180 equation, we get
(y - 79.8) + y = 180
2y - 79.8 = 180
2y = 180 + 79.8
2y = 259.8
y = 259.8/2 = 129.9 degrees.
so x = 129.9 - 79.6 = 50.3 degrees.
See if it worked. x = 129.9 degrees, y = 50.3 degrees, x + y = 180 so we found the correct two angles! :-)
6. Find m2.
Can someone explain how to get the answer to this question please.
Answers
Answer:
m∠2 is 55°
Step-by-step explanation:
Let us revise some facts in geometry
In any triangle, the sum of the measures of its angles is 180°If two line intersected at a point, then they formed two pairs of vertically opposite angles, the vertically opposite angles are equal in measuresWe will use these facts to solve our question
∵ ∠1 is an angle of a triangle
∴ m∠1 + 40° + 85° = 180° ⇒ 1st fact
→ Add the like terms in the left side
∴ m∠1 + 125° = 180°
→ Subtract 125° from both sides
∴ m∠1 + 125° - 125° = 180° - 125°
∴ m∠1 = 55°
∵ ∠1 and ∠2 formed from the intersecting of two lines
∴ ∠1 and ∠2 are vertically opposite angles
∴ m∠1 = m∠2 ⇒ 2nd fact
∵ m∠1 = 55°
∴ m∠2 = 55°
These points are linear.
