Answer:
y = 3x + 2 because there are no value for x.
Step-by-step explanation:
4 squared = 16
Square root of 25 = 5
Equation = 16-5x2
Do 5x2 first because of order of operations
16-10 = 6
Current average = (80 + 93 + 63 + 83 + 83) / 5
= 402 / 5
= 80.4
79 x 6
= 474
what he needs to score on the next test = 474 - 402
= 72
{reassurance = (80 + 93 + 63 + 83 + 83 + 72) / 6
= 474 / 6
= 79}
Answer:
x = 23
Step-by-step explanation:
Exterior angles equals the sum of opposite interior angles.
2x+ 3 + 51 = 100
Combine like terms.
2x + 54 = 100 {Subtract 54 from both sides}
2x = 100 - 54
2x = 46 {Divide both sides by 2}
x = 46/2
x = 23
Answer:
37,143
Step-by-step explanation:
Supplementary angles add to 180 degrees
Let x be one angle
x+106 is the other angle
x + x+106 = 180
Combine like terms
2x+106 =180
Subtract 106 from each side
2x+106-106 =180-106
2x = 74
Divide by 2
2x/2 =74/2
x = 37
The other angle is 37+106 =143
