Step-by-step explanation:
Put the value y.
-2x-8(-5x+22)=14
-2x+40x-176= 14
38x-176 =14
38x = 190
x=5
Now put the value of X to find Y
Y= -5(5)+22= -25+22 = -3
=>X=. 5
=>Y= -3
Answer:
7.25 × 10^6
Step-by-step explanation:
1) put into standard form: 6,000,000 + 1,250,000
2) add: 6,000,000 + 1,250,000= 7,250,000
3) put into scientific notation: 7.25 × 10^6
If I'm doing this correctly, you would need to multiply everything inside the parenthesis by 8. So it would be 8x-24y·8x+24y. I'm sorry if that's not right, but that is my interpretation of the problem. Hope I was of some assistance :)
Answer:
D = 4.2
Step-by-step explanation:
-5.5 ( d - 2 ) = - 12.1
-5.5d + 11 = - 12.1
11 + 12.1 = 5.5d
23.1 = 5.5d
d = 23.1 ÷ 5.5
d = 4.2
