Answer:
See below.
Step-by-step explanation:
a. 973 * 80
= 973 * 8 * 10
= 7784 * 10
= 77,840.
b. 56 * 2000
= 2*56 * 1000
= 112,000.
c. 5.7 * 300
= 5.7 * 3 * 100
= 17.1 * 100
= 1710.
d. 0.46 * 50
= (0.46 * 100) / 2
= 46 / 2
= 23.
<span>I think these are the answers. I think you copied a few of the questions wrong.
x ≥ −8
</span><span>t ≤ −13
</span><span>x ≤ 2
</span><span>d > 0
</span><span>no solution</span>
Answer:
-t + 4.5>7
Step-by-step explanation:
-18 = t
-t = 18
18+4.5 = 22.5
22.5>7
Boom
hope it helps :)
About 55 because 165 divided by 3 is 55
Answer:
c = 2, d = - 3
Step-by-step explanation:
Expand and simplify the left side then compare the coefficients of like terms on both sides.
5(2x + 1) + c(x + d) ← distribute parenthesis
10x + 5 + cx + cd
= x(10 + c) + 5 + cd
Compare like terms on both sides, that is
10 + c = 12 ( subtract 10 from both sides )
c = 2
Then
5 + cd = 5 + 2d and
5 + 2d = - 1 ( subtract 5 from both sides )
2d = - 6 ( divide both sides by 2 )
d = - 3
