Use your knowledge about parentheses and substitution to solve the following:
7. 2(x + 4) + 10 =
8. 3(6x) + 4 =
9. 10(xy) =
10. 5(x + y) =
11. 2(rs) + 4(x)
12. 2(q) + 2(x + t) =
13. 6(7t + 4s) =
14. 9(10x) + 10y =
15. 2x(xy) =
16. r(s)(t) =
17. (r)(s)(t)(x)(y) =
18. (7x + 2Y) =
Answer:
7. 2(x + 4) + 10 =2x+18
8. 3(6x) + 4 = 18x+4
9. 10(xy) = 10xy
10. 5(x + y) =5x+5y
11. 2(rs) + 4(x) = 2(rs+2x)
12. 2(q) + 2(x + t) = 2(q+x+t)
13. 6(7t + 4s) = 42t+24s
14. 9(10x) + 10y = 90x+10y
15. 2x(xy) =2x^2y
16. r(s)(t) =
17. (r)(s)(t)(x)(y) =
18. (7x + 2Y) =

Let's simplify step-by-step.
8h−0.9d−18+5d−2.6h
=8h+−0.9d+−18+5d+−2.6h
Combine Like Terms:
=8h+−0.9d+−18+5d+−2.6h
=(−0.9d+5d)+(8h+−2.6h)+(−18)
=4.1d+5.4h+−18

Research the GDP per capita for the United States. Where does the United States stand in comparison to the European countries you have studied?
Answer:
Step-by-step explanation:
As the chart demonstrates, most European countries (including Germany, Sweden, Denmark and Belgium) if they joined the US, would rank among the poorest one-third of US states on a per-capita GDP basis, and the UK, France, Japan and New Zealand would all rank among America’s very poorest states, below No. 47 West Virginia, and not too far above No. 50 Mississippi. Countries like Italy, S. Korea, Spain, Portugal and Greece would each rank below Mississippi as the poorest states in the country.

From what is shown, they are rectangles, so you will have four points on each grid.
Connect the dots to form the rectangle, since i dont have this sheet i cant demonstrate.
if you dont understand just use this~

Step-by-step explanation:Stuart wants to find the value of 3 3/4 -2 1/3 Before Stuart can subtract, he needs to rewrite both fractions with a common denominator. Drag a number or expression into each box to show how to write equivalent fractions so the new fractions have a common denominator.
Answer:
1 21/50
Step-by-step explanation:
3 3/4 = (3/4 x 4/4) = 3 9/12
2 1/3 = (1/3 x 3/3) = 2 4/12
3 9/12 - 2 4/12 = 1 21/50

ahh please help, i need to determine the slope and y-intercept for each graph. I need to write the equation for the graph in slope-intercept form.
Answer:
Step-by-step explanation:
slope: m = [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]
m = [tex]\frac{3-4}{4-2}[/tex] = - [tex]\frac{1}{2}[/tex]
y-intercept: b = 5
Equation: y = - [tex]\frac{1}{2}[/tex] x + 5
