Let's solve for y.
4x+7y=28
Add -4x to both sides.
4x+7y+−4x=28+−4x
7y=−4x+28
Divide both sides by 7.
7y/7=−4x+28/7
y=−4/7x+4
Answer:
(1, 3)
Step-by-step explanation:
Given the expression
x+y = 4 ... 1
y = 2x+1 ....2
Substitute equation 2 into 1
x + (2x+1) = 4
3x + 1 = 4
3x = 4-1
x = 3/3
x = 1
Since y = 2x + 1
y = 2(1) + 1
y = 3
Hence the solution to the equation is (1,3). This means that the coordinate point on the graph where both lines intersect will be at (1, 3)
Eli received the most votes
Step-by-step explanation:
Given percentages are:
Eli: 30%
Daphne: 27%
Celeste: 25%
Thaddeus: 18%
When a circle chart is used, the sum of all percentages is 100.
In case of finding the largest between the portions, the part with the greater percentage has the greater share in the chart.
According to given percentages, Eli has the highest percentage, which means that Eli received the most votes.
Hence,
Eli received the most votes

Answer:
The probability that at least one is a boy is 0.525
Step-by-step explanation:
P(Baby being a girl) = 0.475
Now, if A is any arbitrary event . Then:
as we know P(A)+ P(not A) = 1
⇒ P(A not happening) = 1 - P(A event happening)
Also, P( baby not being a girl) = P(baby being a boy)
So, P(baby being a boy) = 1 - P( baby being a girl)
= 1 - 0.475 = 0.525
Hence, the probability that at least one is a boy is 0.525
