x = -15
Step-by-step explanation:
1) Four times sum of a number and 10
4(x + 10)
2) is equal to 100 added to 8 times the number
4(x+10) = 8x + 100
x + 10 = 2x + 25
-15 = x
Answer:
1/20 of 2 minutes = 6 seconds
Answer:
√2' = t
Step-by-step explanation:
1 1/2s = 3/5t^2 + 1/3u^2; substitute known values
1 1/2 • 28 = 3/5 • t^2 + 1/3 • -6^2; simplify
42 = 3 • t^2 ÷ 5 + 1/3 • 36
42 = 3 • t^2 ÷ 5 + 12; apply property of subtraction of equality
42 – 12 = 3t^2 ÷ 5 + 12 – 12; simplify
30 = 3t^2 ÷ 5; apply property of multiplication of equality
30 • 5 = 3t^2 ÷ 5 • 5; simplify
6 = 3t^2; apply property of division of equality
6 ÷ 3 = 3t^2 ÷ 3; simplify
2 = t^2
√2' = t
Answer:
yes 80 is a multiple of 4 because 4 × 20 = 80
No solution
It’s no solution because if you would’ve subtracted 4.5z on both sides then the equation would’ve become:
0= -4.25+6.25
Which makes it a no solution since you can’t really solve the equation.
