Answer 1

Answer:

Answer:

The answer is t = 17

Step-by-step explanation:

Sum of angles on a straight line = 180⁰

(2t -7) + 90 + 49= 180

(2t -7) +139 = 180⁰

2t -7) = 180 - 139

2t - 7 = 41

2t = 41 - 7

2t = 34

Divide both sides by 2

t = 17

(0,0); m = -2 write an equation of the line that passes through the given point and has the given slope.

Answers

y=(-2x) is the answer due to the intersecting point being at the origin and the slope being -2. the equation is y=m(x-a)+b with (0, 0) being (a, b) and m obviously equaling -2

Is it true or false an angle bisector cannot be a median

False, if youre talking about the median/bisector of a triangle, an angle bisector can be a median if and only if the bisected angle is the apex of an isosceles or equilateral triangle.

The ratio of the number of CARS to SUVs in a parking lot is 5:2. There are 70 total Vehicles in the parking lot. How many SUVs are there

Answers

Answer:

Since the ratio of cars to SUVs is 5:2, we can assume that there are 5x cars and 2x SUVs, where x is a positive integer.

The total number of cars and SUVs is 5x + 2x = 7x.

Since there are 70 vehicles in total, we can set up the equation 7x = 70.

Simplifying the equation, we get x = 10.

Thus, there are 2x = 2 * 10 = 20 SUVs in the parking lot.

Answer: 20.

5/6+3/7 in simplest fom

Answers

Get a common denominator:

5/6*7/7=35/42

3/7*6/6=18/42

Add the numbers:

35/42+18/42=53/42

This fraction does not simplify, so 53/42 is our final answer.

5/6 + 3/7

Common denominator is needed.

5/6 = 35/42
3/7 = 18/42

Now add

35 + 18 = 53

53/42
53 - 42 = 11

1 and 11/42

a + b +c = 10

a + b - c = 3

find the value of

a + b + 3c

Answers

ok if you look at the first to equations carefully you will see that 2 things have changed between the 2. the "+c" is now "-c" and the "10" is now "3"

if we think about it you will see that c=7. well how do we know. when c or 7 was taken away from the problem it left you with 3

so that means a+b=3

we dont need to know what the exat value of a or b is.

so a+b +3c
(3) + 3(7)
3 + 21
24

a+b+3c=24
