Add -4y to both sides.
3x + 4y + −4y = 10 + −4y
3x = −4y + 10
Divide both sides by 3.
3x /3 = −4y + 10 /3
x= −4 /3 y + 10 /3
Answer: x= −4 /3 y + 10 /3

Three trees are planted. The direct distance from tree A to tree B is 200 feet. The direct distance between tree B and tree C is 300 feet. What is the direct distance between tree A and tree C?
Answer:
500ftStep-by-step explanation:
DISTANCE BETWEEN TWO POINTS
We want to firstly assume that the the three trees lies on the same line
so tress A,B and C are on the same line
Given
The direct distance between A to B= 200 ft
The direct distance between B to C= 300 ft
hence A to C= 200+300= 500ft
let us do a graphical representation for better understanding
A----B-----------C
200ft 300ft
A---------- -----C
500ft
A to C= 500ft
Answer:
Between 100 and 500
Step-by-step explanation:
A to B is 200
And b to c is 300
A to C =500
200-300=100
Answer = Between 100 and 500

A punch recipe uses
2 1/2cups of sherbet to make 24 cups of punch.
How many cups of sherbet will be needed to make 12 cups of punch?
Answer:
1 1/4 cups
Step-by-step explanation:
Make a proportion; 24/2.5 = 12/xDivide 2.5 by two, which is 1.25Answer:
1 1/4 cups of punch.
Step-by-step explanation:
Since 2 1/2 cups of sherbet are needed to make 24 cups, and we need to make 12 cups of punch, it's basically 24 divided by 2. So we need to divide 2 1/2 by 2, which would be 1 1/4 cups.
need help with solving equations
Answer:
No solutions
Step-by-step explanation:
-3(6 - 2x) + 23 = 4 - 1/3(-18x - 2)
~Distribute both sides
-18 + 6x + 23 = 4 + 6x + 2
~Combine like terms
5 + 6x = 6 + 6x
~Subtract 5 to both sides
6x = 6x + 1
~Subtract 6x to both sides
0 = 1

Can someone tell me how I solve this, like explain how I do the steps not just the answer
==================================================
Explanation:
Pick any two rows from the table to form (x,y) points
I'll select the first two rows.
(x1,y1) = (-4,-3) from row 1
(x2,y2) = (0,-2) from row 2
Plug those values into the slope formula
m = (y2-y1)/(x2-x1)
m = (-2-(-3))/(0-(-4))
m = (-2+3)/(0+4)
m = 1/4
The slope is 1/4, which is also the rate of change.

A line passes through points (0, k) and (4,0) and has a slope of –2.5. Which statements are true regarding the graph of the line?
Answer:
A. The equation of the line is y=−2.5x+10.
C. The y-intercept is k.
F. The value of k is 10.
Step-by-step explanation:
A line passes through points (0, k) and (4,0) and has a slope of –2.5. Which statements are true regarding the graph of the line?
A. The equation of the line is y=−2.5x+10.
B. The equation of the line is y=−2.5x.
C. The y-intercept is k.
D. The y-intercept is 4.
E. The value of k is 4.
F. The value of k is 10.
Solution:
The slope of a line is the ratio of the vertical change to the horizontal change. The slope (m) of a line passing through [tex](x_1,y_1)\ and\ (x_2,y_2)[/tex] is:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Given that the line passes through (0, k) and (4,0)
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]-2.5=\frac{0-k}{4-0}\\\\-2.5=\frac{-k}{4}\\\\k=10[/tex]
The equation of the line is given as:
[tex]y-y_1=m(x-x_1)\\\\y-10=-2.5(x-0)\\\\y = -2.5x+10[/tex]
The y intercept is the value of y when x = 0, hence intercept = k
Given the line that passes through points (0, k) and (4,0) and has a slope of –2.5, we need to get the value of "k
The formula for calculating the slope of a line is expressed as:
[tex]m=\frac{y_2-y_1}{x_2-x_1}\\-2.5 = \frac{0-k}{4-0}\\-2.5=\frac{-k}{4} \\Cross \ multiply\\-2.5 \times 4 = -k\\-10 = -k\\k = 10[/tex]
Hence the value of k is 10.

Louisa has 4 yards of fabric. She uses 25 yard of fabric to make a doll dress. How many doll dresses can Louisa make with the fabric? Choose the number line model that shows the answer.
Answer:
D. Number line from 0 to 4 is divided into 20 equal parts. Number line is grouped into 10 equal parts.
Step-by-step explanation:
This are the options:
A. Number line from 0 to 4 is divided into 20 equal parts. Number line is grouped into 4 equal parts.
B. Number line from 0 to 4 is divided into 20 equal parts. Number line is grouped into 8 parts.
C. Number line from 0 to 4 is divided into 20 equal parts. Number line is grouped into 5 equal parts.
D. Number line from 0 to 4 is divided into 20 equal parts. Number line is grouped into 10 equal parts.
Amount of Fabric owned by Louisa = 4 yards
If she uses 2/5 yards to make a doll dress, to get the number of dolls that 4 yards can make we will say:
1 doll = 2/5 fabric
x doll = 4 fabrics
Cross multiply
2/5 * x = 4*1
2x/5 = 4
cross multiply
2x = 20
Divide both sides by 2:
2x/2 = 20/2
x = 10
This means that she can make 10 dolls using 4 yards of fabric.
Hence the correct option will be
D. Number line from 0 to 4 is divided into 20 equal parts. Number line is grouped into 10 equal parts.

Step-by-step explanation:
If both sides, when simplified, equals each other, the answer will be "all real numbers". Simplify the left side. Distribute 2 to all terms within the parenthesis:
2(x + 1) = (2 * x) + (2 * 1) = 2x + 2

Brandt is buying a new set of golf clubs for
$584. If the clubs are on sale now for 30%
off and sales tax is 7%, how much will he
pay in total?
HHEELLPP I HAVE A TEST TOMOROW!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Answer:
Original : $437.416 Rounded to Nearest Cent : 437.42
Step-by-step explanation:
Turn 30% into a decimal which is 0.3. Now multiply 0.3 by 584.
0.3 x 584 = 175.2
Now you have to subtract the answer by the original price, $584.
584 - 175.2 = 408.8
Finnaly, you have to find the sales tax of $408.8. In order to find that, you have to convert 7% into a decimal which is 0.07, then multiply it by 408.8. Then you have to add 408.8 to the following answer.(You can change a percent into a decimal by doing the number divided by 100)
0.07 x 408.8 = 28.616
408.8 + 28.62 = 437.42
Here's your answer. I know I'm late.
The cost of the kit is $437.416
What is discount?A deduction from the usual cost of something, typically given for prompt or advance payment or to a special category of buyers.
Given that, Brandt is buying a new set of golf clubs for $584. If the clubs are on sale now for 30% off and sales tax is 7%, we are asked to how much will he pay in total,
The cost of golf kit will be,
= (100-30)% of 584 + 7% of (100-30)% of 584
= 70% of 584 + 7% of 70% of 584
= 408.8 + 28.616
= 437.416
Hence, the cost of the kit is $437.416

Rebecca decides that this building will be too small at a scale of 1 cm = 3 m. She changes the plan to be at a 1 cm = 4 m scale. What will be the area of the circular pool when it is constructed at this scale?
Answer:
A. 78.5m^2
Step-by-step explanation:
To find the area of a circle you have to do:
Area = πr^2
The diameter is 2.5 x 4 which equals 10 and radius is half the diameter, so 5. Now your equation would be:
Area = π5^2
Solve:
π x 5^2
5^2 = 5 x 5 = 25
π x 25
π ≈ 3.14
3.14 x 25 = 78.5
Answer:
π5^2 ≈ 78.5
