Step-by-step explanation:
The order of operations is applicable in a multip-operations equation. This theorem states the order in which one must do operations in order to get a valid result. Remember the order of operations states;
1) Parenthesis
2) Exponents
3) Multiplication or Division
4) Addition or Subtraction
Solve this equation, keeping the order of operations in mind;
{ [ 3 + 2 - ( 9 - 7 ) + ( 3 + 4 ) ] }
{ [ 3 + 2 - ( 2 ) + ( 7 ) ] }
{ [ 3 + 2 - 2 + 7 ] }
{ [ 5 - 2 + 7 ] }
{ [ 3 + 7 ] }
{ [ 10 ] }

1. Girl Scout Troop 321 started with 25 girls and at the end of the year party there were 31 girls. Gabby
shows her work below to find the percent of change for her troop.
31-25
31
6
31
0.1935
Gabby figures that her troop increased by about 19.4%
Describe and then correct the error Gabby made in finding the percent of change.
Pick what Gabby did wrong.
The real percent of change is:
Answer: 24%
Step-by-step explanation:
Since we are informed that the Girl Scout Troop started with 25 girls and at the end of the year party there were 31 girls. The percentage change will be:
= (31 - 25) / 25 × 100
= 6/25 × 100
= 24%
The error that Gabby made was that she used 31 as the base. This is expressed below:
= 31 - 25) / 31 × 100
= 6/31 × 100
= 19.4%
A butcher has 15 and 3/4 pounds of steaks and portions them into 7 sealed packs. How many pounds does each pack of steak weigh? *
Answer:
9/4 or 2 and 1/4 pounds
Step-by-step explanation:
Convert 15 and 3/4 into an improper fraction
15*4+3 = 63
63/4
63/4 ÷ 7
9/4
Thus, each pack weighs 9/4 pounds
Answer:
2 1/4 pounds each
Step-by-step explanation:
Convert 15 1/4 into a decimal (15.75) then divide by seven (15.75 ÷ 7 = 2.25)
and then convert 2.25 back into a fraction, 25 is 1/4 of 100 so the answer is 2 1/4

Answer:
m<E = [tex]77^{o}[/tex]
Step-by-step explanation:
From the diagram, ΔACE and ΔBDE are similar. So that comparing its angles, we have;
(8x + 4) = (9x - 5)
8x + 4 = 9x - 5
5 + 4 = 9x - 8x
x = 9
Thus,
(8x + 4) = 8(9) + 4 = 76
(9x - 5) = 9(9) - 5 = 76
3x = 3(9) = 27
From ΔACE,
3x + (8x + 4) + m<E = 180 (sum of angles in a triangle)
27 + 76 + m<E = 180
m<E = 180 - 103
m<E = [tex]77^{o}[/tex]

When xb= 12, y = 8. Find x when y = 12
Answer:
If it is direct proportionality, then y = kx where k is a constant. Use the given information to find k:
8 = k(12) ⇒ k = 8/12 = 2/3
y = (2/3) x
For y = 12,
12 = (2/3) x ⇒ x = (3/2)*12 = 18
x = 18 when y = 12

Lana wants to graph the height of an amusement park ride as it travels along the track.
A. The ride begins by climbing slowly up a hill.
B. It moves straight along a flat piece of track.
C. The ride glides quickly downhill.
D. It slowly climbs another hill.
Drag a segment to each box to show the shape of the graph for that interval.
Answer:
I can’t do this for you, you have to drag the segments into the boxes. The fifth over is A. then you do the first line segment. Then the third. for D you do the fifth over

Answer:
$498.75
Step-by-step explanation:
Why it would be $498.75 is 500 - 25 is 475 then if you do 5% of 475 you get 23.75 and you will add that to the 475 and you will get $498.75.
2) What is the slope in the equation y=2x + 3?
Answer:
2
Step-by-step explanation:
y = mx + b
y = 2x + 3
m is the slope. So of we look in the equation 2 is in the m place so 2 is the slope. Hope this helps, thank you :) !!
Pls help me with this work
Answer:
They are similar because they both have like terms in parenthesis.
Step-by-step explanation:
As long as you have like terms, the equation is the same. You never have to worry about the number before the variable being the same. As long as the variable is the same, you have like terms and that is like terms in the equation. TO SUM IT UP: They both have like terms and that is why they are similar.

PLS HELP ME I BEG I WILL MARK YOU BRAINLIEST
Answer:
Step-by-step explanation:
Scale factor = 1 : 7
a)Let the length of the house in the scale drawing = x
1:7 :: x : 21
Product of means = Product of extremes
7*x = 1* 21
x = [tex]\frac{1*21}{7}[/tex]
x = 3
Length of the house in the scale drawing = 3 in
b) Height of the real house =y
1 : 7 :: 4 : y
Product of extremes = product of means
1 * y = 7*4
y = 7*4
y = 28
Height of real house = 28 feet
please help me with this angle question :)
Answer:
its an acute angle
Step-by-step explanation:
its an acute angle be cause its small than a right angle
Answer:
angle AED = 70 degrees
angle x = 10 degrees
Step-by-step explanation:
since angle ABD = 110 degrees, major arc AED = 2(110) = 220 degrees
since angle ADB = 40 degrees, minor arc AB = 2(40) = 80 degrees
minor arc BD = 360 - 220 - 80 = 60 degrees
arc AB + arc BD = arc ABD
arc ABD = 80 + 60 = 140 degrees
angle AED = 1/2 (140) = 70 degrees
angle EAD = angle AED because isosceles
arc ED = 2(70) = 140 degrees
arc AE = arc AED - arc ED = 80 degrees
angle x = 1/2(arc AE - arc BD) = 1/2(80 -60) = 10 degrees

Answer:
$16
Step-by-step explanation:
Answer:
Estimate: $16
Exact amount: $15.98
Step-by-step explanation:
To find the estimate amount of money she has left, we will add everything up and subtract it from $45.12.
$7.89 + $21.25 = $29.14
$45.12 - $29.14 = 15.98
Now lets round your answer to $16. Therefore, the estimated amount that she has left is $16. And based on the calculations above, we can see that the exact amount of money she has left is $15.98.
