D. (−1, 3)
I WILL MARK AS BRAINLIEST IF CORRECT!
Answer:
[tex]x = - 1[/tex]
[tex]y = 3[/tex]
Step-by-step explanation:
[tex]y - 4x = 7(eqn \: 1)[/tex]
[tex]2y + 4x = 2(eqn \: 2)[/tex]
[tex]solving \: by \: eliminating \: one \: variable[/tex]
[tex](y - 4x = 7)[/tex]
[tex] + (2y + 4x = 2)[/tex]
[tex]3y = 9[/tex]
[tex]y = 3[/tex]
[tex]y - 4x = 7[/tex]
[tex]3 - 4x = 7[/tex]
[tex] - 4x = 7 - 3[/tex]
[tex] \frac{ - 4x}{ - 4} = \frac{4}{ - 4} [/tex]
[tex]x = - 1[/tex]
The solution to this system of linear equations will be (–1, 3). Then the correct option is D.
What is the solution of the equation?The solution of the equation means the value of the unknown or variable.
The equations are given below.
y − 4x = 7 ...1
2y + 4x = 2 ...2
Add both equations, then we have
3y = 9
y = 3
Put y = 3 in equation 1, then we have
3 − 4x = 7
4x = –4
x = –1
The solution to this system of linear equations will be (–1, 3).
Then the correct option is D.

Yolanda has a 1/6 -cup ladle that she uses to pour gravy over potatoes. She uses one full ladle for each serving of potatoes. Yolanda has 6 cups of gravy. How many servings of potatoes can she make?
Answer: For 6 cups of gravy, Yolanda will have 36 servings of potatoes
Step-by-step explanation:
Step 1
Since Yolanda has a 1/6-cup of ladle for one full serving
Then for every serving the 1/6- cup ladle is used and can be expressed as
1 serving =1/6-cup of ladle
Step 2--- Solving
Serving of potatoes for 1 cup is
1 serving =1/6 cup of ladle
?? servings=1 cup of ladle ( cross multiply)
= 1 x 6/1 = 6 servings
Therefore 6 cups of gravy = 6 servings x 6 = 36 servings of potatoes

A single coin is flipped four times. A) Use an organizational strategy to construct the sample space for this situation. B) How many different outcomes are possible?
Step-by-step explanation:
- A single coin is known to have 2 sides (The head H and the tail T).
The total number of sample space for n number of coins is expressed as 2ⁿ where
n is the total number of coins flipped.
If a single coin is flipped four times, the total outcome will be expressed as;
2⁴ = 16
Hence there are 16 different possible outcomes.
- To construct the sample space (the 16 possible outcomes)
For one flipped coin, the sample space is represented by the set S₁
S₁ = {H, T}
H is Head
T is Tail
For two flipped coin, the sample space is represented by the set S₂
S₂ = S₁×S₁
S₂ = {H, T}×{H,T}
S₂ ={HH, HT, TH, TT}
For three flipped coin, the sample space is represented by the set S₃
S₃ = S₂×S₁
S₃ = {HH, HT, TH, TT}×{H,T}
S₃ = {HHH, HHT, HTH, HTT, THH, THT, TTH, TTT}
For four flipped coin, the sample space is represented by the set S₄
S₄ = S₃×S₁
S₄ = {HHH, HHT, HTH, HTT, THH, THT, TTH, TTT}×{H,T}
S₄ ={HHHH, HHHT, HHTH, HHTT, HTHH, HTHT, HTTH, HTTT, THHH, THHT, THTH, THTT, TTHH, TTHT, TTTH, TTTT}
Hence the sample space for a single coin flipped 4times is given by the set;
S₄ ={HHHH, HHHT, HHTH, HHTT, HTHH, HTHT, HTTH, HTTT, THHH, THHT, THTH, THTT, TTHH, TTHT, TTTH, TTTT} where;
n(S₄) = 16

how do i solve for c 0.2(c - 3)= -10
Answer: c = -47
Step-by-step explanation:
1. Divide both sides
2. Move the constant to the right
3. Calculate
Answer:
c = -47
Step-by-step explanation:
Here's how!
0.2(c - 3) = -10 (distribute 0.2 to c and -3)
0.2c - 0.6 = -10 (add 0.6 to both sides)
0.2c = -9.4 (divide by 0.2 on both sides)
c = -47
Plug in
0.2(-47 - 3) = -10 (add -47 and -3)
0.2(-50) = -10 (distribute)
-10 = -10

A house as purchases for $ 6780000.
a- Write the purchase price in million?
b- Write the purchase price in millions nearest to an integer.
Answer:
Please check the explanation.
Step-by-step explanation:
a)
As there are 1000000 units in 1 million
i.e.
1 million = 1000000 units
A house as purchases for $6780000.
Thus, the purchase price in million will be:
6780000/1000000 = 6.78 million
b)
purchase price in millions nearest to an integer
As the number we are rounding is followed by 7, so will be round the number up.
Therefore,
$6780000 rounded to the nearest million = $7,000,000

The 7th grade students at Palm Coast Middle School made some apple pies for a bake sale. The school cafeteria also donated 9 pies toward the effort. All the pies at the sale were cut into 8 pieces. If at least 224 pieces of pie were sold in all, how many pies did the students bake? (shown on number lines)
Answer: at least 19
Step-by-step explanation:
Since there were at least 224 pieces of pie sold. We would divide the amount of slices of pie sold (224) by the amount of slices in each pie (8). Which would be (28) pies sold and then we would subtract the (9) pies that the school gave us, and we would end up with (19) pies.

Line M is represented by the following equation: x − y = 8
Which equation completes the system that is satisfied by the solution (18, 10)? (4 points)
a
2x − y = 26
b
x + y = 18
c
2x − 2y = 36
d
x − y = −28
Answer:Let's plug in (18,10) into each answer choice until we find the one that has it as a solution.
A) 2x - y = 26
2(18) - 10 = 26
36 - 10 = 26
26 = 26
Your answer is A.
I'll just do the rest to show that you the they are incorrect.
B) x + y = 18
18 + 10 = 18
28 ≠ 18
C) 2x - 2y = 36
2(18) - 2(10) = 36
36 - 20 = 36
16 ≠ 36
D) x - y = -28
18 - 10 = -28
8 ≠ -28
Your answer is A) 2x - y = 26.
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
2(18) - (10) = 26
36 - 10 = 26
