Can you guys help me with this

Answer:

x= -2, y= -9

Step-by-step explanation:

let -4x+y=-1 be [1]

and y=2x-5 be [2]

Sub [2] into [1]

-4x+(2x-5)=-1

-4x + 2x -5 = -1

-2x -5 = -1

-2x = 4

2x = -4

x = -2

Sub x=-2 into [2]

y=2(-2)-5

y=-4-5

y=-9

Answer:

17.2

Step-by-step explanation:

Answer:

73

Step-by-step explanation:

According to Triangle Sum Theorem, the 3 interior angles of a triangle adds up to 180 degrees.

So, you can take the other 2 interior angles to find the third on:

180-72-35=73

<1=73 degrees

Answer:

[tex] \sf \: x = 8[/tex]

Step-by-step explanation:

Given equation,

→ 11x + (-4x) = 56

Now the value of x will be,

→ 11x + (-4x) = 56

→ 11x - 4x = 56

→ 7x = 56

→ x = 56/7

→ [ x = 8 ]

Hence, the value of x is 8.

Answer:

67°

Step-by-step explanation:

There are a total of 180° in a triangle.

Step 1:

180° - 46° = 134°

Step 2:

134° / 2 = 67°

x° = 67°

Hope this helps! :D

The value of each x is 67

Answer:

4m + 6  

Step-by-step explanation:

Hello There!

We can simplify the expression by distributing the 2 to what is inside of the parenthesis ( 3 and 2m)

3 * 2 = 6

2 * 2m = 4m

so the expression 2(3 + 2m) simplified would be

4m + 6  

Answer: 6+4m

Step-by-step explanation:

Let's take our equation first

2(3+2m)

Now we need to distribute the 2 into the parenthesis'

This would mean we need to multiply 2 by 3 and 2m

our answer would be

6+4m

WE CAN'T SIMPLIFY THIS ANYMORE

Answer: 10

Step-by-step explanation:

16 x 5/8

reduce the numbers to 2 x 5

cross out 16 and 8 and you have 5 left, 16 divided by 8 = 2

2 x 5 = 10

hope this makes sense and helps you :)

Given:

17 quarts of soil are used to completely fill 4 flower pots.

To find:

The number of quarts hold by each pot if each pot holds the same amount of soil.

Solution:

Let [tex]x[/tex] be the number of quarts hold by each pot.

Total number of quarts hold by 4 flower pots = [tex]4x[/tex]

It is given that, 17 quarts of soil are used to completely fill 4 flower pots.

[tex]4x=17[/tex]

[tex]x=\dfrac{17}{4}[/tex]

[tex]x=4.25[/tex]

Therefore, the each pot holds 4.25 quarts of soil.

A car is rented for $40 per day plus $0.25 per mile driven. The total is $45.50-  40 + 0.25x + 45.50

Karen buys four t-shirts for $45.50. The three red t-shirts each cost 4 times the price of one blue t-shirt.- x + 3(4x) = 45.50

Finn buys a toy boat for $45.50 including tax He was charged 7% sales tax on the original price.- X+0.07% = 45.50

Nick buys a sweater and a jacket for $45.50. The jacket costs 4 times as much as the sweater- 1 X + 4x = 45.50

Step-by-step explanation:

Answer:

x = 3√2 , y = 6

Step-by-step explanation:

In given triangle,

3√2 = x

and y is hypotenuse.

Using Pythagoras theorem

hypotenuse = √Perpendicular² + Base²

hypotenuse = √(3√2)² + (3√2)²

hypotenuse = √18 + 18

hypotenuse = √36

hypotenuse = 6

So,

x = 3√2 , y = 6

Answer: [tex]2*0.54^x[/tex]

Step-by-step explanation:

Answer:

y = 5x + 14

Step-by-step explanation:

An equation consists of y = mx + b. The m is the slope, which we already know is 5.

To find the y-intercept, plug the coordinates into the equation so far, which is y = 5x + b.

y = 5x + b

4 = 5(-2) + b

4 = -10 + b

14 = b

So the equations is y = 5x + 14.
