Answer:
m = -5.3
Step-by-step explanation:
-39.75 = 7.5m
Divide both sides by 7.5 to get m alone
-39.75/7.5 = 7.5m/7.5
-5.3 = m
Hope this helps:)
Answer:
x = 78º
y = 35º
Step-by-step explanation:
These are isosceles triangles
two angles are congruent
-----------------------------
x + 51 + 51 = 180
x = 180 - 102
x = 78º
y + y + 110 = 180
2y = 70
y = 35º
<span>Megan
went to beach 34 times last summer.
June = x
July = 6 * june
August = 2 * june
Thus Let’s find the value of june, which is the value of x as a variable:
Equation:
x + 6x + 2x = 34
Solution:
=> x + 6x + 2x = 34
=> 9x = 34
=> 9x / 9 = 34 / 9
=> x = 3.7778, since this is a decimal, let’s round this off to 3.78
Let’s check our answer
=> 4 + 6(4) + 2(4)
=> 4 + 24 + 8
=> 36 approximately.</span>
18/50 people = 0.36
36% like the clothing store.
Then with 125 people..
125 * 0.36 = 45 people
Solve x+4y = 13 for x by subtracting 4y from both sides.
We end up with x = -4y+13.
Since x and -4y+13 are the same, we can replace every x in the first equation with -4y+13
2x-3y = -29
2( x ) - 3y = -29
2( -4y+13 ) - 3y = -29 ... x is replaced with -4y+13
The answer is choice B
