Answer:
Fred needs 3 cups of sugar to make 4 batches
Fred needs 3/8 cups of sugar to make 1/2 batches
Step-by-step explanation:
1 batch of cookies = 3/4 cups of sugar
how many cups of sugar does Fred need to make 4 batches
Let x = cups of sugar needed
Batches : Cups of sugar
1 : 3/4 = 4 : x
1 ÷ 3/4 = 4/x
1 * 4/3 = 4/x
4/3 = 4/x
Cross product
4 * x = 3 * 4
4x = 12
x = 12/4
x = 3 cups of sugar
Fred needs 3 cups of sugar to make 4 batches
how many cups of sugar does Fred need to make 1/2 batches?
Let x = cups of sugar needed
Batches : Cups of sugar
1 : 3/4 = 1/2 : x
1 ÷ 3/4 = 1/2 ÷ x
1 * 4/3 = 1/2 * 1/x
4/3 = 1/2x
Cross product
4 * 2x = 3 * 1
8x = 3
x = 3/8 cups of sugar
Fred needs 3/8 cups of sugar to make 1/2 batches

For four Fridays in June, Grace earned $21.50, $29.75, $32.00, and $15.25 from babysitting.
In July, she earned $8 more for babysitting four Fridays than she did in June.
What is the increase in the mean for July compared to June?
Round the answer to the nearest penny.
Answer:
$2
Step-by-step explanation:
Its actually quite simple.
first find the mean for june.
add $21.50 + $29.75 + $32.00 + $15.25
that is equal to 98.5
then divide by 4.
that is 24.625
do not round to the nearest penny yet.
now you need to find the mean for july.
just add $8 to the total amount you made in june to find the total amount you made in july.
that is 106.5
then divide that by four because you worked four fridays in july as well.
that is 26.625.
finally you need to find the difference between 26.625 and 24.625.
26.625-24.625= 2
and ta-da!!!
the answer us $2.

Answer:
A. x = 2, y = 12
Step-by-step explanation:
You can solve this problem using similar triangles; you know the triangles are similar because each of the two legs of the triangles are cut in half, meaning the line 5x - 3 is parallel to x + 12. Because of the nature of this figure (the line that is length 5x - 3 cuts the triangle exactly halfway), you can write an equation to find x:
2(5x - 3) = x + 12 (this is a property of triangles when a line is parallel to a base and intersects the triangle at half of that base's height. The line would be half the base)
10x - 6 = x + 12 (simplify)
9x - 6 = 12 (subtract x from both sides)
9x = 18 (add 6 to both sides)
x = 2 (divide both sides by 9)
At this point, you could just click A since that's the only problem where x = 2, but for the sake of properly explaining this problem, I'll continue to find y.
In the image, y + 8 is equal to 2y - 4, shown by the short lines intersecting each side signifying congruence. Now, you can write an equation for this and solve:
y + 8 = 2y - 4
8 = y - 4 (subtract y from both sides)
y - 4 = 8 (switch it around so y is on the left; you don't have to do this, but I think it makes the problem more comfortable to solve)
y = 12 (add 4 to both sides)
Algebraically, determine the exact value of x for the
equation 85(2)0.4x = 6000.
Answer: 14,575
Step-by-step explanation:
85(2) 0.4x = 6000 Multiply 85 times 2
170 + 0.4x = 6000 Subtract 170 from both sides
0.4x = 5830 Divide 5830 by 0.4
x = 14,575

Consider the following pair of equations:
y = −2x + 8
y = x − 1
Explain how you will solve the pair of equations by substitution. Show all the steps and write the solution in (x, y) form.
Answer:
(3,2)
Step-by-step explanation:
y = -2x + 8
y = x-1
Substitute x-1 for y in the equation y = -2x + 8. x-1 = -2x + 8
Use the Additive Property to move the
constant terms to one side of the equation. x-1 = -2x + 8
+1 +1
x = -2x + 9
Now do the same to the variable terms. +2x +2x
3x = 9
Divide both sides of the equation by the
constant in the variable term. ÷3 = ÷3
x = 3
To find y, simply substitute the value of x into
one of the original equations. y = x-1
y = 3-1
Solve: y = 2
The solution is (3, 2).

Khaya is delivering groceries to his mother who stays 8km from the shop. How long will it take him to cover this distance if he drives at an average speed of 65km/h? Give your answer rounded to the nearest minute.
Answer:
7.385 minutes
Step-by-step explanation:
Given that :
Average speed = 65km/hr
The distance covered = 8km
The time taken Given the information above :
Recall:
Speed = distance / time
Time taken = distance / speed
Time taken = 8km / 65km/hr
Time taken = 0.1230769 hr
Time taken = 0.1230769 * 60 = 7.385 minutes
The time taken to cover this distance is 7.3848 minutes
What is speed?Speed is the change of an object's distance within a specified period of time.
Mathematically, speed can be calculated by using the relation:
Speed = distance/timeFrom the given information:
The average speed = 65 km/hThe distance = 8 kmFrom the above formula, we can make the time the subject of the formula:
Speed = distance/timeBy cross multiplying
Time = distance/speedTime = 8 km / 65 km/hTime = 0.12308 hourWe all know that:
60 seconds = 1 minute60 minutes = 1 hourThus, time(t) = (0.12308 × 60) minutes
Time(t) = 7.3848 minutes
