Answer:
The answer to your question is letter c and d.
Step-by-step explanation:
A. 15 × 9 = 135 and 135 – 75 = 60 This answer is not correct because it is not necessary to multiply the # members by the cost of each tree, the answer is incorrect.
B. 3 × 15 = 45 and 45 + 15 = 60 This answer is incorrect because it's using a number 3 that is not part of the data.
C. 45 ÷ 9 = 5 and 5 × 15 = 75
. This answer is correct, first finds the number of tree bought by each member and after that multiply it by the cost of each tree.
D. 45 × 15 = 675 and 675 ÷ 9 = 75 This answer is correct, first found the total cost and after divide it by the number of members.
Answer:
<em>4</em><em>*</em><em>5x-7</em><em>=</em><em>20</em>
4*5(-7)-7=20
20(-7)-7=20
-140-7=20
-140=20+7
-140=27
=27+140
<u>=</u><u>167</u>
<em>-</em><em>3x</em><em>+</em><em>7</em><em>=</em><em>28</em>
-3(6)+7=28
-3(6)=28-7
-18=21
=21+18
<u>=</u><u>39</u>
<em>2x</em><em>+</em><em>3</em><em>=-7</em>
2(-5)+3=-7
2(-5)=-7-3
-10=-10
=-10+10
<u>=</u><u>0</u>

5 (x+2x)
5 (3x)
15x
Please try leaving out the "I'm so bad at math" part. It doesn't help.
The given inequality is <span>4x + y > −6. Because of the > symbol, we must use a dashed line, not a solid one. Let's solve this for y: y > -4x - 6.
This (dashed) line has a slope of -4 and a y-intercept of (0,-6).
Plot (0,-6). Then, with your pencil pt. on that, move 1 unit to the right and then 4 units down. Plot a new point there, at (1, -10). Draw your dashed line thru those 2 pts. Then, because we have y > -4x - 6, shade the area ABOVE this line. Done.</span>
