Answer:
Step-by-step explanation:
y = -2/3 x multiply both sides the first equation by 6
6y = -4x Add 4x to both sides.
6y + 4x = 0
<u>-9y +4x = - 40 </u> Subtract the bottom equation
15y = - 40 Divide by 15
y = -40/15
y = - 2.7
======================
6y = -4x
6*(-2.67) = -4x
-16 = - 4x
x = - 16/-4
x = 4
Answer:
pie times radius square is equal to 147
when pie is 3, radius square is 49
radius is equal to 7
actual pie r square is 22/7 times 7 times 7 is 154
Step-by-step explanation:
ans is 154
The answer is no solution
Answer:
3^7
Step-by-step explanation:
it’s the same as
(3^6)(3^1)
when you multiply the same number but with different exponent, you’ll add the exponent together, the number stays tha same.
3^(6+1)
3^7
Answer:
2nd option
Step-by-step explanation:
the quadrilateral has 1 pair of parallel sides and is therefore a trapezoid.
• each lower base angle is supplementary to the upper base angle on the same side, that is
∠ 1 + ∠ 2 = 180° , so
x + x + 50 = 180
2x + 50 = 180 ( subtract 50 from both sides )
2x = 130 ( divide both sides by 2 )
x = 65
then
∠ 1 = x = 65°
∠ 2 = x + 50 = 65 + 50 = 115°
