Andre is trying to solve the equation 2x plus 6 equals 3x minus 8. The result of Andre’s first step was -x + 6 = -8. What was Andre’s first step?
Answers
Answer:
C. Subtracted 3x from each side.
Step-by-step explanation:
I'm not 100% sure that this is correct but it's the only one that makes sense in my brain. But I'm going to explain anyways.
2x + 6 = 3x - 8 (initial equation)
subtract 3x from 2x and it leaves you with -xsubtract 3x from 3x and it leaves you with 0 which is why there is no number there anymore.It could also be D. Subtract 6 from each side, which is why I'm confused. Hopefully this helps, sorry if it doesn't. But happy holidays! :))

The ratio of cherry candies to grape candies in a bag is 3:5. After your friend eats half of the grape flavored candies and only one cherry flavored candy, the ratio of cherry to grape candies is 7:6. How many candies are left in the bag?
Answers
Answer:
65
Step-by-step explanation:
The computation of the number of candies left in the bag is as follows:
Let us assume the cherry candies be c ;
And, grape candies be g
Now the ratio between them is 3:5
And, in the case when half of the candies are eaten and one cherry is also eaten so the ratio is
(c - 1) ÷ (g ÷ 2) = 7 ÷ 6
After subsitution
It would be
(3 ÷ 5g - 1) ÷ (g ÷ 2) = 7 ÷ 6
Now after solving it,
g = 60
And, the c = 35
As the candies are half so it would be 30 now
So, the number of candies together is
= 35 + 30
= 65
Find the perimeter of the triangle
Answers
Answer:
60 ft
Step-by-step explanation:
(x+13) = (3x-1) = (6x-22) since the triangle is equaililateral
(x+13) = (3x-1) (we only need to chose 2)
-2x=-14
x=7
after this, we just need to plug in the number for x
3(7)-1= 20--->since the triangle has 3 congruent sides, they all have the distance, so 20x3=60

A) The distance between -5 and 0 is a Positive 5 because it takes 5 positive spots to go from -5 to 0.
B) The Absolute Value of -5 is 5. (Absolute Value means the distance from that number from zero) Is takes 5 spots to get to -5.
I hope this helps, and Happy Holidays! :)
Answer:
1) 5 units
2) 5
Step-by-step explanation:
absolute value is basiclly the opposite for example 4 would be -4 and -7 would be 7
also if it has lines like this: |2| it stays as it is so |3| is still 3 and |-5| is still 5

a. exactly one of the two requirements;
b. at least one of the requirements;
c. neither requirement.
Answers
Answer:
65
85
Step-by-step explanation:
Exactly one of the two requirement
Maths only = 45 - 20 = 25
Science only = 60 - 20 = 40
Exactly one = (25 + 40) = 65
B.) Atleast one :
(25 + 40 + 20) = 85
C) Neither :
140 - 85 = 55

Answers
Answer:
Which number is the slope of the line shown by the equation?
B. 40
Which number is the y-intercept
D.75
Step-by-step explanation:
The formula for the Equation of a line =
y = mx+b
where:
m is the slope and b is the y-intercept.
Hence, interpreting the above question:
On a two-week job, a repairman works a total of 70 hours,He charges 75$ plus 40$ per hour.
x is the number of hours and y is the total fee.
Hence, the Equation we have is:
y = $40 × x + 75
y = 40x + 75
Comparing with the Equation of a line formula
= y = mx+b
Therefore:
The slope of the line = 40
The y intercept = 75

Answer:
y = 3/4 x + 1/4
Step-by-step explanation:
line through the points (1, 1), (5, 4)
slope (m) = (4 - 1) / (5 - 1) = 3/4
y = mx + b b = y - mx ... for point (1 , 1)
b = 1 - 3/4 = 1/4

Expand the brackets. Collect like terms. Get the same values on each side so it’s easier to isolate a. Divide 9 from 9a so that u get a by itself and this gives u the answer if 36/9 or 4.
Answer:
a = 4
Step-by-step explanation:
first distrubute the 3 and then 2 in the equations to whatever is inside the parantheses:
3 ( 1-9a) + 22a = 2(2a-9) -15
3 - 27a + 22a = 4a - 18 - 15
then combine the terms:
3 - 5a = 4a -33
then isolate the variables and constants to one side, for example move the 5a to the right side of the equation and move the 33 to the left side of the equaiton and then simplfy
36 = 9a
divide both sides by 9
a = 4

Bill wanted to try out different water craft he went 62 mikes downstream in a motor boat and 27 mikes down stream on a jest ski his speed on the jet ski was 10 mph faster than the motor boat bill spent a total of 4 hours on the water what was his speed in the motor boat
Answers
Answer:
The speed on motorboat is 20 mph
Step-by-step explanation:
here, we want to find the speed on the motorboat
if he has a speed of x mph on the motor boat, his speed on the ski will be (x + 10) mph
The total hours is 4 hours
Mathematically; speed = distance/time
Time on ski is 27/x+ 10
Time on motor boat is 62/x
The addition of both is 4
Thus;
27/(x + 10) + 62/x = 4
27(x) + 62(x + 10) = 4(x)(x + 10)
27x + 62x + 620 = 4(x^2 + 10x)
89x + 620 = 4x^2 + 40x
4x^2 -49x-620 = 0
using the quadratic formula;
{-b ± √(b^2-4ac)}/2a
where a = 4, b = -49 and c = -620
= 49 ± √(-49)^2-4(4)(-620)/8
So we have
49+ 111/8 or 49-111/8
Speed cannot be negative
(49 + 111)/8
= 20 mph

find the values of x in [0,360) which satisfy 2cot^2x=-3cscx
Answers
Answer:
The values of x is -30 degrees and undefined
None of these values fall within the given range
Thus, no value within the given range is the solution to the equation
Step-by-step explanation:
Here, we want to find the value of x that works for the equation in the selected range
2cot^2x = -3csc x
Mathematically, from trigonometry;
cot^2x = csc^2x - 1
Substitute this above
2(csc^2x - 1)= -3csc x
let csc x = b
2(b^2-1) = -3b
2b^2 - 2 + 3b = 0
2b^2 + 3b - 2 = 0
2b^2 + 4b - b - 2 = 0
2b(b+ 2) - 1( b + 2) = 0
(2b-1)(b + 2) = 0
2b = 1
b = -2
b = 1/2 = 0.5
or b = -2
Recall;
csc x = b
x = csc^-1 b
x = csc^-1 0.5
x = undefined
Secondly;
b = -2
x = csc^-1 (-2)
x = -30 degrees
As we can see , between the points
0 ≤ x < 360
None of our answers fall in these range
