11 + 3x = −15 − 4x
U subtract 11 from both sides 11+3x-11=-15-4x-11
Refine3x=-4x-26
Add 4x to both sides
3x+4x=-4x-26+4x
Refine7x=-26
Divide both sides by 7
<span>7x/7 = -26/7</span>
Refinex= -26/7
Answer:
A) 
Step-by-step explanation:
in a 30-60-90 triangle the sides, respectively, are in the ratio of 1 : : 2
Answer:
6
Step-by-step explanation:
they both would be equal to each other.
5x-7 = 23
5x = 30. (add 7 to both sides)
x = 6. (divide 5 to both sides)
Answer:
The volume of a prism on its own = 248.5cm^3
The volume of a cylinder = 87.92cm^3
Step-by-step explanation:
The volume does not change for the prism as the hole was drilled.
We can show the drilled space with v(l) and (p) for prism V
v(l) 248.5p - 87.92p + 87.92p
= 248.5p
The answer would be 0.05 because the five is in the hundredths place
