Need help getting stuck on this problem

Mathematics

stepan [7]3 years ago

Answer:

  • Variable x in first equation

Step-by-step explanation:

<u>Given system</u>

  • x = 5y - 1
  • x + 2y = 13

Variables in this system are x and y.

Isolating a variable means rearranging the equation so that a variable of our interest is on its own in one side of the equal sign.

We see <u>variable x is isolated </u>in the first equation.

In the second equation both of the variables are on the same side so they are not isolated.

An angle measures 32° more than the measure of its complementary angle. What is the measure of each angle?
Leviafan [203]

Answer:

29° ; 61°

Step-by-step explanation:

Let one angle  = x°

Other angle = (x + 32)°

x + x + 32 = 90   {given they are complementary}

2x + 32 = 90

2x = 90 -32

2x = 58

x = 58/2

x = 29

One angle  = 29°

Other angle = 29 + 32 = 61°

A(0,-1)
B(3√3/3, 2)

Slope of AB = (y₂ - y₁)/(x₂-x₁)
Slope = (2-1)/(√3/3 , -0)

Slope = 1/√3/3 = 1/√3 = √3/3

OR SLOPE = tan(a°) = √3/3 and a° = 30°

Can someone help? I suck at this
Usimov [2.4K]

Answer:

23 cm squared

Step-by-step explanation:

Split the shape into two shapes.

<u>Shape one:</u>

5 x 3 = 15 cm squared

<u>Shape two:</u>

7 - 3 = 4 (length of a side of the second shape)

4 x 2 = 8 cm squared

A car travels at a speed of 85 miles per hour. How far will it travel in 15 mins?
marusya05 [52]

In this question, we're trying to find how many miles a car travels in 15 minutes.

We know that the car travels at 85 mph.

However, we need to know how many miles it travels per minute.

To find this, we would divide 85 by 60.

85 ÷ 60 = 1.4166

The car drives at a speed of about 1.42 per minute.

We need to know how far it goes in 15 minutes, so multiply 1.42 by 15.

1.42 · 15 = 21.3

The car travels at a approximately 21.3 miles in 15 minutes.
