Answer:
Mark has 24
Don has 79
Step-by-step explanation:
Let x = marbles mark has
don has 3x+7
Together they have 103
mark + don = 103
x+ (3x+7) = 103
Combine like terms
4x+7 = 103
Subtract 7
4x = 96
Divide by 4
x = 96/4
x =24
Mark has 24
Don has 103 -24
Done has 79
Its 153. you can’t exactly divide 8 by 1544. if you wanted it to be a whole number it would be 1544 by 8. which is 152
Answer:
144m
Step-by-step explanation:
To find the area of trapezoidal prism, you would have to multiple the area of the trapezoid by the height of the prism.
The formula for trapezoid is 1/2(L+W) x H
So the area of trapezoid would be 1/2(10+6) x 2 = 16
The height is 9m so it would be 16 x 9, which is 144m
Answer:
$87.90
Step-by-step explanation:
Let the amount of money Hashim had be $Y. As such, if he gives his mother $28, he would have $Y - $28 left.
If he had $15.20 less than his sister and his sister had $75.10, then we can say that what he had left $Y - $28 is equivalent to the difference between $75.10 and $15.20.
This is
$Y - $28 = $75.10 - $15.20
Y = $28 + $75.10 - $15.20
= $87.90
