Which equation will solve the following word problem? Four roommates share the cost of an apartment: rent, electricity, and gas. Rent costs $1200/month and gas costs $50/month. Each roommate pays $345/month. How much is the electric bill per month?


($1200 + $50)/4 = E + $345


($1200 + $50 + $345)/4 = E


($1200 + $50 + E)/4 = $345


($345)4 + E = $1200 + $50

Answer:

its closer to 1....

Step-by-step explanation:

1/2 is half

so...

half of 15 is 7.5

8 is larger than 7.5

so that makes it closer to one

Answer : The surface area of triangular prism is 1080 in².

Step-by-step explanation :

Formula used to calculate the surface area of triangular prism is:

Surface area of triangular prism = (2 × Area of triangle) + Area of all rectangle

Area of triangle = [tex]\frac{1}{2}\times base\times height[/tex]

Area of rectangle = length × breadth

In the given triangular prism, there are 2 triangles and 3 different rectangles.

Surface area of triangular prism = [tex](2\times \frac{1}{2}\times base\times height)[/tex] + Area of rectangle ABCF + Area of rectangle ABDE + Area of rectangle CDEF

Surface area of triangular prism = [tex](2\times \frac{1}{2}\times 10\times 24)+(24\times 14)+(26\times 14)+(14\times 10)[/tex]

Surface area of triangular prism = 1080 in²

Therefore, the surface area of triangular prism is 1080 in².

Answer: Nothing

Step-by-step explanation: There aren't any numbers that multiply to equal 6 but add to be -1.

There aren't any numbers that multiply to equal 6 but add to be -1 but we can say -6 and positive 1.

An equation is an expression that shows the relationship between two or more numbers and variables.A mathematical equation is a statement with two equal sides and an equal sign in between. example, 4 + 6 = 10. Both 4 + 6 and 10 can be seen on the left and right sides of the equal sign, respectively.

For that , we need to try solving it first using the method of substitution in which we express one variable in other variable's form and then it can substitute this value in other equation to get linear equation in one variable.

We need to find the number that equals 6 but adds to -1.

We can see that there aren't any numbers that multiply to equal 6 but add to be -1.

So, we conclude that number could be -6 and positive 1.

Answer: 8

Step-by-step explanation:

From the question, we are informed that Hilary has 48 building blocks in the red bucket which is 6 times as many blocks in the green bucket.

Let the number of building blocks that are in the green bucket be represented by x.

Based on the scenario given in the question, this will be:

6 × x = 48.

6x = 48

x = 48/6.

x = 8

This means that there are 8 green building blocks

Answer:

x = 15 degrees

Step-by-step explanation:

This is a right angle, since we know that a right angle contains 90 degrees, we can form an equation.

[tex]30+4x=90[/tex]

Now, we solve for x.

[tex]-30+30+ 4x = -30+90[/tex]

[tex]4x=60[/tex]

[tex]\frac{4x}{4}=\frac{90}{4}[/tex]

[tex]x=15[/tex]

12 students play defense. 1st step.  6/9 of 27 is 18.  2nd. the ratio of the students playing offense to the total number of students playing soccer is 1 to 3 which means the total amount of students is '3', in the ratio it's 3 because it's simplified (i like to think of it as 'groups'). since we know that there are a total of 18 students and there's 3 total 'groups' we divide 18 into 3 which is 6. so there's 6 students in each group. we subtract 6 (1 group) from 18 ( the total number of students) which is 12, so there are 12 students playing defense. if you wrote the ratio again without simplifying it would be  6:18

Answer:

x = - 6 y = 13

Step-by-step explanation:

we know when the diagonals bisect it divides into two equal parts so

-4x - 2 = -3x + 4

-4x + 3x = 4 + 2

- x = 6

x = - 6

Now

2y + 8 = 3y - 5

3y - 2y = 8 + 5

y = 13

Answer:

Let's solve your equation step-by-step.

−5(3−x)+4=5x−11

Step 1: Simplify both sides of the equation.

−5(3−x)+4=5x−11

(−5)(3)+(−5)(−x)+4=5x+−11(Distribute)

−15+5x+4=5x+−11

(5x)+(−15+4)=5x−11(Combine Like Terms)

5x+−11=5x−11

5x−11=5x−11

Step 2: Subtract 5x from both sides.

5x−11−5x=5x−11−5x

−11=−11

Step 3: Add 11 to both sides.

−11+11=−11+11
