When you use the substitution method you need to plug a value into the corresponding variable of another equation.
In this occasion,"-6y-7" can be plugged into the x of "16x-4y=18" because it represents the x.
16(-6y-7)-4y=18
Distribute 16 into the parentheses
-96y-112-4y=18
Combine like terms
-96y-4y-112+112=18+112
-100y=130
Divide by -100 to get y by itself
y=-1.3 or -13/10
Now plug the y into any equation...I chose "x = -6y - 7" but it doesn't matter
x= -6(-1.3)-7
x=-14.8 or 4/5
Answer:
Step-by-step explanation:
1. 16x-4y=18
4x-9/2:2x+9/8
4x-9/2:m=4
y=4x-9/2
2. x=-6y-7
1/6x-7/6:-6x-7

Darius sees a new store advertising 10 of the same packs of paper clips for $41.50. Which statement best describes the strategy Darius should use to get the best price for each pack?
Answer:
$4.150/packStep-by-step explanation:
Given the price of 10packs as $41.50, we can express it as;
10 packs = $41.50
To get the equivalent price of 1 pack, we will say;
1 pack = $x
Solving both equalities for x;
10 packs = $41.50
1 pack = $x
cross multiply
10 * x = 1 * 41.50
10x = 41.50
Divide both sides by 10
10x/10 = 41.50/10
x = 4.150
Hence the price for each pack is $4.150

Monday's high temperature in Denver, Colorado was 25°F. The low temperature was
-4° F. What was the difference between the high and low temperatures?
Answer:
The difference between the high and low temperatures is 29°F
Step-by-step explanation:
Subtraction
The high temperature in Denver, Colorado was 25°F on Monday.
The low temperature was -4°F in the same place.
We are required to find the difference between the high and low temperatures.
We need to subtract 25 and -4:
Difference = 25°F - (-4°F)
Note we change the sign of the subtraction multiplying (-1) by (-1);
Difference = 25°F + 4°F
Difference = 29°F
The difference between the high and low temperatures is 29°F

Madison is a high school basketball player. How many points would Madison score in a game if she made 8 free throws (worth one point each) and 6 three point shots?
How many points would Madison score in a game if she made x free throws and y
three point shots?
Answer:
26 and 1x+3y on Delta math
Step-by-step explanation:
Explanation:
Each free throw scores 1 point, so 8 free throws would score 1\times 81×8 or 8 points. Each three point shot scores 3 points, so 6 three point shots would score 3\times 63×6 or 18 points. Therefore, the total number of points Madison would score is 26.

Answer:
There are sixteen 15-cent stamps and eight 20-cent stamps.
Step-by-step explanation:
Stamp collector has:
15c stamps
20c stamps
Total value is $4
x($0.15) + y($0.20) = $4.00
The # of 15c stamps is 8 - than 3 * the # of 20c stamps; 15c = 8 - 3c
x = 3y - 8
(3y-8)(0.15)+y(0.20) = $4.00
0.45)y-1.20+(0.20)y = 4.00
(0.65)y-1.20 = 4.00
(0.65)y = 5.20
y = 8
x = 3(8)-8 = 16
There are sixteen 15-cent stamps and eight 20-cent stamps.
Check:
16($0.15)+8($0.20) = $2.40+$1.60 = $4.00

the ratio the ratio of two numbers is 5:6 . find the sum of two numbers is 55. find the number
Answer:
25 and 30
Step-by-step explanation:
Given the ratio of 2 numbers is 5 : 6 = 5x : 6x ( x is a multiplier ), then
5x + 6x = 55, that is
11x = 55 ( divide both sides by 11 )
x = 5
Thus
5x = 5 × 5 = 25
6x = 6 × 5 = 30
Then the 2 numbers are 25 and 30
