Answer:
7x - 7
Step-by-step explanation:
Product of x and 7 = 7x
7 minus 7x
7x - 7
Hence the expression is :
7x - 7
25+6=31
So you have to multiply 0.36 by 1500 to get your answer
Answer is 540
Plz correct me if I’m wrong
Answer:
x = 3/7y - 13/7
Step-by-step explanation:
7x-3y=-13
+3y +3y Add 3y to both sides
7x = 3y - 13 Divide both sides by 7
x = 3/7y - 13/7
Answer:
2a + 30
Step-by-step explanation:
break it down so it is 4(a+5)
then work out -2(a-5)
so 4 x a then 4 x 5 which gives 4a + 20
then -2 x a then -2 x -5 which gives -2a + 10
then when you have 4a + 20 -2a + 10
do 4a - 2a which is 2a
do 20 + 10 which is 30
so the answer comes to 2a + 30
if anything doesnt seem right just comment and i will correct
