Substituting the equation x = 2y + 3 into the equation y=-3x - 4 will produce the equation y = -3(2y + 3) - 4
What are linear equations?Linear equations are equations that have constant average rates of change, slope or gradient
How to determine the solution to the system?A system of linear equations is a collection of at least two linear equations.
In this case, the system of equations is given as
x = 2y + 3
y = -3x - 4
Considering the first equation
x = 2y + 3
Considering the second equation
y = -3x - 4
Substitute the first equation in the second equation
y = -3(2y + 3) - 4
Hence, substituting the equation x = 2y + 3 into the equation y=-3x - 4 will produce the equation y = -3(2y + 3) - 4

The diameter of a semicircle is 2 miles. What is the semicircles perimiter?
Answer:
The perimeter of the semi circle is gonna be π or 3.14
Step-by-step explanation:
So we know semi circle
The diameter is 2 so that basically also means the main circle diameter is also 2
we trying to find it’s circumference (perimeter)
We can follow the equation
C=πd
In this case d is 2
So 2π
And since that is full circle, half circle would be π

Mya bought 6 slices of bread for $2.40 at her local grocery
store. How much would a package with 10 slices cost at the price
per slice?
Answer:
$4.00
Step-by-step explanation:
Find how much it would cost for one slice of bread by dividing 2.40 by 6 to get .4.
So .40 cents is for 1 slice of bread. If you got 10 slices of bread (multiply 10 by .4) you would get 4.
So it costs 4 dollars for 10 slices of bread.

In a survey, 250 adults and children were asked whether they know how to swim. The survey data are shown in the relative frequency table. Can swim Cannot swim Adults Total 0.34 0.06 Children 0.48 0.12 Total What percentage of the people surveyed are adults? O A. 40% O B. 6% O C. 82% OD. 34%
Answer:
A 40%
Step-by-step explanation:
The percentage of the people surveyed that are adults is; A: 40%
How to interpret Frequency Table?
We are given;
Sample size of adults and children = 250
From the table, we see that;
Proportion of adults that can swim = 0.34
Proportion of adults that can't swim = 0.06
Thus;
Total proportion of Adults in the survey = 0.34 + 0.06
Total proportion of Adults in the survey = 0.40
Thus, percentage of people surveyed that are adults = 0.40 * 100% = 40%

carol used 1 1/4 cups of flour in 2 muffins How many cups of flour are needed to make 12 similar muffin
Answer:
B
Step-by-step explanation:
Hey there! first, we divide 1 1/4 by 2 to get how much flour is used to make one muffin then we multiply 0.625by 12 because 1 1/4 ÷ 2 = 0.625
12 × 0.625 = 7.5
(7.5 is equivalent to 7 1/2)
Carol need 7[tex]\frac{1}{2}[/tex] cups of flour for 12 muffins.
What is division?The division in mathematics is one kind of operation. In this process, we split the expressions or numbers into the same number of parts.
Given:
Carol used 1[tex]\frac{1}{4}[/tex] cups of flour in 2 muffins.
That means, Carol used 5/4 cups of flour in 2 muffins.
Unit rate = 2x4/5
= 8/5
When we have 12 muffins,
then flour = 12x 5/8
= 60/8
= 7[tex]\frac{1}{2}[/tex] cups of flour.
Therefore, 7[tex]\frac{1}{2}[/tex] cups of flour for 12 muffins.

When Joseph moved into a new house, he planted two trees in his backyard. At the time of planting, Tree A was 16 inches tall and Tree B was 37 inches tall. Each year thereafter, Tree A grew by 6 inches per year and Tree B grew by 3 inches per year. Let AA represent the height of Tree A tt years after being planted and let BB represent the height of Tree B tt years after being planted. Write an equation for each situation, in terms of t,t, and determine the interval of time, t,t, when Tree A is taller than Tree B.
The tree A is 3t taller than tree B.
Equation to represent tree A = 16 + 6t
Equation to represent Tree B= 37+ 7t
What is linear equation?A linear equation is an algebraic equation of the form y=mx+b. involving only a constant and a first-order (linear) term, where m is the slope and b is the y-intercept.
Given that : Tree A was 16 inches tall and Tree B was 37 inches tall.
Tree after 't' year
A= 16 + 6t
B = 37 + 7t
so,
A-B= 16 + 6t -(37+3t)
= 16 + 6t - 37 -3t
= 3t- 21
As tree A grew 2 times the tree B
then t'= 2t
A'- B'= 3t' -21
= 3(2t)-21
=6t -21
Thus, (A'- B')(A-B) = 6t-21- (3t-21)
= 6t-3t
= 3t
Hence the tree A is 3t taller than tree B
Equation to represent Tree A = 16 + 6t
Tree B= 37+ 7t
