Math question now.
When I am 6 my brother is half my age. How old will my brother be when I am 70?
Answer:
67
Step-by-step explanation:
Your brother is three years younger than you, so when you're 70, he'll be three years younger, 67.

Answer:
35 years old
Step-by-step explanation:
Since your brother is half your age, that means it should be exact. 70 is not a number than would have an even split, so you would have to have either an odd number such as 5. 40 plus 40 is 80, which is to high. 30 plus 30 is 60, too low. 35 plus 35 is 70 exact. Hope this helped! Also, I dont know if this was trick question, either way, he should be half. So if you were 10, he would be 5. If you were 18, he would be 9.
Answer:
1.4/5+8/9
2.17/18-3/7
Step-by-step explanation:4/5+8/9 so you want the bottem two to be the same right so your ganna multapliy the 5 times 9 and 9 times 5 the 4 times 9 and 8 times 5 then you will have
36/45 and then40/45 then ad them and you will have about 2
2.is about 1 or about 0 i say about 1
Answer:
7.56 quarts of antifreeze in the resulting mixture, and 37.8% of the resulting mixture is antifreeze.
Step-by-step explanation:
8 * .45= 3.6 quarts antifreeze
12 * .33= 3.96 quarts antifreeze
3.6 + 3.96= 7.56 quarts of antifreeze in the resulting mixture
7.56 quarts/ 20 quarts (12 + 8) * 100= 37.8%
In the combined solution, there are 7.56 quarts of anti-freeze, which equals 37.8% of the total solution.
To solve this problem, we first need to calculate how many quarts of anti-freeze are in each solution, then add them together.
First, we have 8 quarts of a solution that is 45% anti-freeze. To find how many quarts of the solution is anti-freeze, we multiply the total amount by the percentage: 8 quarts * 0.45 = 3.6 quarts anti-freeze.
Next, we have 12 quarts of a solution that is 33% anti-freeze. Doing the same calculation as before, 12 quarts * 0.33 = 3.96 quarts anti-freeze.
Now, to find the total quarts of anti-freeze in the combined solution, we simply add the two amounts together: 3.6 quarts + 3.96 quarts = 7.56 quarts.
The total amount of solution is 8 quarts (from the first solution) + 12 quarts (from the second) = 20 quarts.
To find the percent of anti-freeze in the final solution, we divide the total amount of anti-freeze by the total amount of solution: (7.56 quarts / 20 quarts) * 100 = 37.8%. Therefore, the resulting mixture is 37.8% anti-freeze.

What is the equation of the line in point-slope form?
4
= {(x + 4)
Oy+4=;
O y-4 = 2(x + 4)
N
Oy - 0 = 2(x-4)
Oy - 4 = 2(x -0)

-2.
2.
the equation of the line in slope-intercept form is:
y = (1/2)x - 2
A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included. Sometimes, the aforementioned is referred to as a "linear equation of two variables," with y and x serving as the variables.
From the graph, two points on the line are (-4, -4) and (4,0),
The formula for the slope of a line is:
m = (y₂ - y₁) / (x₁ - x₁)
where (x₁, y₁) and (x₂, y₂) are two points on the line.
Using the given points (-4, -4) and (4, 0), we can calculate the slope:
m = (0 - (-4)) / (4 - (-4))
m = 4 / 8
m = 1/2
Now that we know the slope, we can use the slope-intercept form of a line, which is:
y = mx + b
where m is the slope and b is the y-intercept.
To find the y-intercept, we can use one of the givenpoints on the line. Let's use the point (-4, -4):
y = mx + b
-4 = (1/2)(-4) + b
-4 = -2 + b
b = -2
Therefore, the slope-intercept form of the line is y = (1/2)x - 2.

Answer:
A
Step-by-step explanation:
For point-slope form, you need a point and the slope.
y - y₁ = m(x - x₁)
Looking at the graph, the points you have are (4, 0) and (-4, -4). You can use these points to find the slope. Divide the difference of the y's by the difference of the x's/
-4 - 0 = -4
-4 - 4 = -8
-4/-8 = 1/2
The slope is 1/2. This cancels out choices C and D.
With the point (-4, -4), A is the answer.
Answer:
3.16
Step-by-step explanation:
Three is equal to well, 3.
Sixteen hundredths gives you 0.16.
Three and sixteenth hundredths is the same as saying 3 and 0.16, which is just 3.16.
