What is the value of x? Angle 1 and Angle 2 are complementary.

1 answer:

5 0

Sum of two complementary angles= 180°
angle 1 + angle 2 = 180°
x + 2x+30 = 180
3x = 180 - 30
3x = 150
x = 150/3
x = 50

so angle 1 = 50°
angle 2 = 2x + 30
= 2*50+30
= 130°

Noah solved an equation as shown below and found that the equation has infinitely many solutions.–3(x+4)+2x=2(x – 6)– 3x–3x– 12+

Svetllana [295]

–3(x+4) +2x = 2(x – 6) – 3x

–3x– 12 +2x = 2x– 12– 3x

–x – 12= –x – 12

0 = 0

Answer:

a. Noah is correct because the two sides of the equation are equivalent expressions.

What is this problem

sergeinik [125]

Answer:

$m=A-\frac{2n}{Z}$

Step-by-step explanation:

Multiply by 2:

2n = Z(A - m)

Divide by Z:

$\frac{2n}{Z} =A-m$

Subtract A:

$-m=\frac{2n}{Z}-A$

Multiply by -1:

$m=A-\frac{2n}{Z}$

Alexis and Tosha challenged each other to a typing test. Alexis typed 54 words in one minute, which was 120% of the Tasha typed.

garik1379 [7]

Words of Tasha = A
A x 120/100=54
simplify 120/100=6/5
A x 6/5=54
divide both side by 6/5
A=54/(6/5)
A=54x5/6
A=45
Tasha typed 45 words
