Answer:
40
Step-by-step explanation:
4 lots of 10 is 10+10+10+10 or 4 x 10
Well it would be 200 × 8 which would equal to 1600
<span>4x+2(3x-9)=42
first we want to distribute the 2 using the distributive property
4x+6x-18=42
Then we simplify
</span><span>10x-18=42
we add 18 to both sides
10x=60
divide both side by 10
x=6</span>
Question 4 is Choice A
Question 5 is Choice B
Question 6 is Choice C
Question 7 is Choice B
These are relatively simple it’s just understanding the relations of x and y values :)
