solve this system using elimination. 3x - 4y = -5, -10x + 4 = 12
Answer:
x = -4/5, y = 13/20
Step-by-step explanation:
-10x + 4 = 12
-10x = 8
x = -4/5
3x - 4y = -5
3(-4/5) - 4y = -5
-12/5 - 4y = -5
-4y = -13/5
y = 13/20
Double check:
3x - 4y = -5
3(-4/5) - 4(13/20) = -5
-12/5 - 13 = -5 (true)
A trapezoid has an area of 40 square feet. It also has a base of 6 feet and 10
another base of 4 feet. What is the height?"
Answer:
[tex]h = 8 \: ft[/tex]
Step-by-step explanation:
Height of trapezoid formula:
[tex]h = 2 \times \frac{area}{a + b} [/tex]
Given:
Area: 40 square feet
a: 6 feet
b:4 feet
Using the given information,
[tex]h = 2 \times \frac{40}{6 + 4} [/tex]
Add the numbers in the denominator
[tex]h = 2 \times \frac{40}{10} [/tex]
Reduce the fraction with 10
[tex]h = 2 \times 4[/tex]
Answer:
[tex]h = 8 \: feet[/tex]

A recipe uses 5 cups of milk to make 20 servings. If the same amount
of milk is used for each serving, how many servings can be made from
two pints?
1 gallon 4 quarts
1 quart 2 pints
1 pint 2 cups
1 cup = 8 fluid ounces
Before you try that problem, answer the question
below.
How many cups will you need to find the number
of servings for?
Answer:
16 servings
Step-by-step explanation:
The recipe would use 2 pints or 4 cups of milk. 1 cup of milk is equal to 4 servings (20/5 = 4), so 4 cups would make 16 servings.
1 pint is equal to 2 cups so 2 pints will be 4 cups.
The number of servings 2 pints will make is 16 servings.
What is a unit rate?A unit rate means a rate for one of something.
It is written as a ratio with 1 as the denominator.
We have,
5 cups of milk = 20 servings
Multiplying 1/5 on both sides.
1/5 x 5 cups of milk = 1/5 x 20 servings
This means,
1 cup of milk = 4 servings
We know that,
1 pint = 2 cups
Multiplying 2 on both sides
2 x 1 pints = 2 x 2 cups
2 pints = 4 cups
If,
1 cup = 4 servings
4 cups = 4 x 4 servings
4 cups = 16 servings
Thus the number of servings 2 pints will make is 16 servings.

(x - 2)/6 = (x + 9)/9
Cross multiply
9(x - 2) = 6(x + 9)
9x - 18 = 6x + 54
Collect like terms
9x - 6x = 18 + 54
3x = 72
Divide both sides by 3
x = 72/3
x = 24
Select three ratios that are equivalent to
11
:
1
11:1
Answer: To solve this problem you must apply the procedure shown below:
1. You have the following ratio given in the problem above:
11:1
2. You can rewrite that ratio as below:
11/1=11
3. Then, to find three equivalent ratios, you only need to multiply the numerator (11) and the denominator (11) by the sam number. Therefore, you have:
11x2/1x2=22/2=11
11x3/1x3=33/3=11
11x4/1x4=44/4=11
Therefore, as you can see, the answer is:
22:2
33:3
44:4

y and 106 are supplementary angles, in other words,
y+106 = 180
y = 74
All the angles in a quadrilateral added up is equal to 360 degrees, so
x+74+74+119 = 360

The probability of getting not blue marble is [tex]\frac{7}{8}[/tex].
What is probability?
Probability is a measure of happening or non-happening of the outcomes of a random experiment.
Probability formulaP(E) = number of favorable outcomes/ total number of outcomes
According to the given question.
Total number of red marbles = 5
Total number of yellow marbles = 4
Total number of green marbles = 5
Total number of blue marbles = 2
⇒ Total number of marbles = 5 + 4 + 5 + 2 = 16
So, total number of outcomes = 16
Now, probability of getting blue marble = [tex]\frac{2}{16} = \frac{1}{8}[/tex]
Therefore, the probability of getting not blue marble = [tex]1 -\frac{1}{8} =\frac{7}{8}[/tex]
Hence, the probability of getting not blue marble is [tex]\frac{7}{8}[/tex].
