Answer:
x = 19.5
Step-by-step explanation:
-2x + 7 = -32 (subtract 7 on both sides)
-7 -7
-2x = -39 (Divide by -2)
x = 19.5
Answer:
first take the like terms of the equation take 7to the other side to make x as a subject of the formula then divide both side by -2 u will get 19.5 as the answer

Please answer the question pls & ty
Answer:
37
Step-by-step explanation:
20 + 13 = 33
so 70 - 33 = 37 so the answer is 37
Answer+explanation
so subtract the diffference of 20 and 13 from 70
so first we find the difference and then subtract that from 70
use parenthases so
difference of 20 and 13 is equal to (20-13)
subtract that from 70
70-(20-13)
so you would do the pemdas and get 7 for the inside parethasees then do
70-7=63
You scored 53 in fight 1 and 103 in fight 2

Here the error is
[tex]\pi {r}^{2} [/tex]
It should have been ,
[tex]2\pi {r}^{2} [/tex]
Step-by-step explanation:
Corrected formula:
[tex]2\pi {r}^{2} + 2\pi rh[/tex]
[tex] = 2\pi ({5}^{2}) + 2\pi(5)(10.6)[/tex]

Answer:
D. (43 +60) +40
Step-by-step explanation:
The purpose of changing the grouping in addition problems is to simplify the mental effort required as much as possible. This will generally mean grouping ...
"complementary" numbers, numbers with the same number of leading or trailing zeros, numbers with the same sign, and fractions with the same denominator.AnalysisA. Numbers ending in 0 are already grouped; no change is needed.
B. Fractions with the same denominator are already grouped; no change is needed.
C. Numbers with the same (negative) sign are already grouped; no change is needed.
D. Numbers ending in zero could be grouped to make addition easier:
43 +(60 +40) . . . . regrouping would be useful
We also note that in A and D, the sum of numbers ending in zero is 100, so these numbers are "complements" of each other. This is another reason for grouping them together.

What is the value of c in the following equation: 29.4 + c = 62
A. 91.4
B. 33
C. 32.4
D. 32.6
Answer:
D) 32.6
Step-by-step explanation:
This question is asked to find the value of "c", a variable.
We can rewrite the equation like this: 62 = 29.4 + c.
So, something + 29.4 = 62.
62 - 29.4 = 32.6.

Write the equation of the line in slope-intercept form using y=mx+b
Answer:
y = -1/6x + 5
Step-by-step explanation:
Slope is -1/6 and y-intercept is 5
Answer:
y=[tex]\frac{-1}{6}[/tex]x+5
Step-by-step explanation:
y=mx+b
m= slope
b= y-intercept
-1/6 is the slope because it is the unknown variable
5 is the y-intercept because it hits a perfect point on the y-axis
to find the slope i used rise/run the rise is -1 and the run is 6
the rise is negative because it is going to the left and essentially on a full graph that would be negative
hopefully this helps :) have a nice day !!
Charlie is re-landscaping his back yard and uses a coordinate plane to map the yard out. There is a pine tree located at (-5, 5); the edge of a shed is located at (-5, 1) and the edge of a sandbox is located at (2, 5). He plans to cover the triangular area formed by these three points with gravel. What area of the yard will be covered in gravel? Note: On the coordinate plane, each gridline represents 2 feet.
56 square feet
112 square feet
14 square feet
28 square feet
Answer:
A. 56 square feet
Step-by-step explanation:
8 ft * 14 ft = 112 ft
112 ft/2 = 56 ft

Please help I dont know what to do. I have already done the graph but all I need is x,y box and equation
Write the equation of the line in slope-intercept form using y=mx+b
answer:
y=1x-50
step-by-step explanation:
y=mx+b
m=slope
b=y-intercept
x=unknown variable
to find the slope i used rise/run
my rise was 3 and my run was also 3
3÷3=1
the slope is going to the right making it positive
the y-intercept is -50 because that is where the line hits the y-axis
good luck :) hopefully this helps
