Solve the system of equations by substitution.
3x + 4y - 12
x + 7y = 8
Step-by-step explanation:
[tex]3x + 4y = 12 \\ x + 7y = 8 \\ x = 8 - 7y \\ 3(8 - 7y) + 4y = 12 \\ 24 - 21y + 4y = 12 \\ 12 = 17y \\ y = 0.705 \\ x = 8 - 7(0.705) = 3.065 = 3.07[/tex]

Step-by-step explanation:
Jim is making salsa. His recipe calls for 3 1 3 cups of tomato sauce for every 1 6 cups of cilantro. If Jim has 1 cup of cilantro, how many cups of tomato sauce will he need?
Answer: 20 cups of tomato
Step-by-step explanation:
From the question, we are informed that Jim is making salsa and that his recipe calls for 3 1/3 cups of tomato sauce for every 1/6 cups of cilantro.
If Jim has 1 cup of cilantro, thus simply means that he has multiplied the previous cup of cilantro by:
= 1 ÷ 1/6
= 1 × 6/1
= 6
Therefore, we would also multiply the cups of tomato by 6. This will be:
= 3 1/3 × 6
= 10/3 × 6
= 20 cups of tomato

Answer: D
Step-by-step explanation:
The graph that represents the inequality [tex]y+ 2 > -3x - 3[/tex] is graph d
The inequality is given as:
[tex]y+ 2 > -3x - 3[/tex]
Subtract 2 from both sides of the inequality
[tex]y+ 2 -2 > -3x - 3 -2[/tex]
[tex]y > -3x - 5[/tex]
See attachment for the graph of [tex]y > -3x - 5[/tex]
The graph that matches the attached graph is graph (d)

Do these ratios form a proportion 12/16 and 15/20
Answer:
This is a proportion
Step-by-step explanation:
Cross multiply:
12 * 20 = 16 * 15
Simplifying:
12 * 20 = 16 * 15
Multiply 12 * 20
240 = 16 * 15
Multiply 16 * 15
240 = 240
Add '-240' to each side of the equation.
240 + -240 = 240 + -240
Combine like terms: 240 + -240 = 0
0 = 240 + -240
Combine like terms: 240 + -240 = 0
0 = 0
Solving
0 = 0

the sum of two and a number is less than five
Answer:
Please check the explanation.
Step-by-step explanation:
Given the English statement
''The sum of two and number is less than five''.
Let us breakdown the statement.
Let 'n' be the number. The sum of two and number = 2 + nWe know that the less than symbol is denoted by '<' which is used for comparison.
Thus, the statement 'The sum of two and a number is less than five' is algebraically represented as:
2 + n < 5Let us solve the algebraic expression.
[tex]2+n<5[/tex]
Subtract 2 from both sides
[tex]2+n-2<5-2[/tex]
Simplify
[tex]n<3[/tex]
Thus, the solution is:
[tex]2+n<5\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:n<3\:\\ \:\mathrm{Interval\:Notation:}&\:\left(-\infty \:,\:3\right)\end{bmatrix}[/tex]

Step-by-step explanation:
13=blue blankets 7=red blankets
First, we need to know how many blankets there are in total.
13+7=20
Now, we don't need the seven anymore. Our ratio is blue blankets to total blankets.
13/20
Now, we need to know how many blue blankets there are in percentage.
13/20 = x/100
Next step: 13 times 100 is divided by 20
x= 13(100)÷20
x=1300÷20
x= 65

Write the equation of the line in slope-intercept form (y = mx + b) that has a slope of 4 and passes through the point (0,2).
Answer:
I need a graph.
Step-by-step explanation:
You can also use rise over run to help you. However if you are stating me that 4 is slope. Then it will be y=4x+ something because I am not sure if 2 is the y intercept even though its on the y-axis.
James is a botanist studying the production of beans by two types of bean plants.
He noticed that the string bean plant produced 30% more beans than the lima bean
plants. Based on James' observation, if the string bean plants produced 130 string
beans, how many lima beans did the lima bean plant produce?
Answer:
100 lima beans
Step-by-step explanation:
We can write an equation with s = string beans and l = lima beans:
s = 1.3l
We can now plug in 130 = s to get:
130 = 1.3l
We divide both sides by 1.3 and get:
100 = l
That means the lima bean plant produced 100 lima beans
Answer:
91
Step-by-step explanation:
130 * 30% =
130 * 0.3 =
39
130 - 39 = 91

2. Four big water bottles can hold 8 gallons of water. How much water can ten big water bottles
hold?
Answer:
16 1/2 gallons of water.
Step-by-step explanation:
Since 4 bottles can hold 8 gallons, and you need to know how much 10 can hold, you can multiply 4 and 8 times 2 so you get 8 and 16, and then if you choose 10 instead of 8 instead you would get the result of 10 bottles being able to hold 16 1/2 gallons of water.
