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.

Ben has a collection of baseball cards. He has a total of 1,600 cards. Of the baseball cards, 35% are dated before 1980, 25% are dated from 1980 to 2000, and
the rest are dated after 2000.
How many baseball cards in Ben's collection are dated after 2000?
Answer:
640 cards
Step-by-step explanation:
If the rest are dated after 2000, that means that 40% are dated after 2000, since 25% + 35% = 60%
To find how many are dated after 2000, multiply 1,600 by 0.4:
1,600(0.6) = 640
So, 640 of the baseball cards are dated after 2000
Surprising survey revealed that 32% of the 475 girls at mason Junior high school were left handed, while only 12% of the 525 boys were left handed. Which is closest to the number of left-hander girls at mason Junior high school?
Answer: See explanation
Step-by-step explanation:
You didn't give the options but let.me solve the number of left handed girls and you then choose the closest answer to the value that I get.
Surprising survey revealed that 32% of the 475 girls at mason Junior high school were left handed. Therefore, the number of left handed girls will be:
= 32% × 475
= 32/100 × 475
= 0.32 × 475
= 152 left handed girls

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

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 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

Underwood Farms had 242 pumkins at the start of November . 12 visitors brought 2 pumkins wach by November 10th. How many pumkind does the farm have left?
Answer:
Total pumpkins left = 254
Step-by-step explanation:
Total pumpkins available = 242
12 visitors brought 2 pumkins each by November 10th.
Total pumpkins brought = 12 × 2
= 24 pumpkins
How many pumkind does the farm have left?
Total pumpkins left = Total pumpkins available + total pumpkins brought
= 242 + 12
= 254
Total pumpkins left = 254

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
