Anita and Joelle bowled together and their combined total score for one game was 425 points. Anita’s score was 40 less than twic

wariber [46]

Call Anita's score $"y"$ and Joelle's score $"x"$ .

1) "<span>their combined total score for one game was 425 points"
</span>Therefore $x+y=425$

2)"Anita’s score was 40 less than twice Joelle’s."
Therefore $y=2x-40$

Substitute:
$x+2x-40=425$

Solve:
$3x=465$
$x=155$

Backsubstitute:
$y=2x-40$
$y=2(155)-40$
$y=270$

Work out the height of a parallelogram with a base of 10m and an area of 60m2

noname [10]

Area formula of a parallelogram is
A = base x height

Given are the
Area = 60 m² and base = 10 m

Substitute the given:

60 = 10h (divide by 10 to find value of h)
$\frac{60}{10} = \frac{10h}{10}$ (10 and 10 cancels out)

h = 6
The height of a parallelogram with a base of 10m and an area of 60m² is 6m
