They both are complementary angles i.e their sum must equals 90°
4x+ 31 + 6x + 39 = 90
10x + 70 = 90
10x = 90-70
10x = 20
x = 2
we have to find angle ADC
just put the value of x in that expression for that angle.
angle ADC = 6x + 39 = 6 (2)+39 = 12 + 39 = 51°
Answer:
x + 4y = 4
4y = 4 - x
multiply both sides by 1/4
y = 1/4( 4- x)
y = 1- 1/4x
Answer:
The computer can perform 1051050 calculations in 10 seconds.
Step-by-step explanation:
1. Put the quantity of calculations the computer can perform in 1 second:

2. Multiply the quantity of calculations by 10 seconds:

Note that the units of seconds are cancelled as they appear on the numerator and the denominator, and the final response unit is given in calculations number.
The computer can perform 1051050 calculations in 10 seconds.
