Answer:

Step-by-step explanation:

If you add the first equation up you get 2z+6 by combining like terms

if you see A a is equal to 3z+6 so a doesn’t work

If you look at B b is equal to z+12 so b doesn’t work

finally C if you distibute it out you get 2(z)+2(3) which equal 2z+6 which works

Find the measure of each angle

Leno4ka [110]

Since this triangle is an isosceles triangle, two of its angles are going to be equal. We know that all the angles in a triangle are equal to 180o.

Step 1: 180 - 98 = 82

Step 2: divide the sum of the two angles (82) to give me the measurement of one of the angles

82/2 = 41

I can travel 250 miles in 90 minutes, how far can i get in 6 hours

german

90 minutes = 1.5 hours.

Divide total miles driven by the time to find how many miles are driven in 1 hour:

250 miles / 1.5 hours = 166 2/3 miles per hour.

Multiply the miles driven in one hour by 6 hours:

166 2/3 x 6 = 1000 miles

The sum of a number and 15

ollegr [7]

Answer:

x + 15

Step-by-step explanation:

The problem is in word form. Write the problem in <u>algebraic form</u>, which means using numbers and symbols (like + - ÷ x).

Take the key word:

'sum' - This means the answer when you <u>add numbers</u>. To add you use the + <u>plus sign</u>.

The sum of a number and 15 means adding a number and 15.

There is no equal sign because the question does not say "equals" or "is".

<u>Choose a variable</u> to represent "a number". I will choose the letter 'x'. Add 15 to 'x'.

x + 15

Which number completes the system of linear

LiRa [457]

The number that completes the System of Linear Inequalities represented by the Graph y >= 2x – 2 and x + 4y > = is -12. Hence, x + 4y $\geq$ -12

<h3>What is a System of Linear Inequalities?</h3>

A collection of linear inequalities in the same variables is referred to as a system of linear inequalities. Any ordered pair that fulfills all of the inequalities is the solution.

<h3>What is the calculation to prove the above assertion?</h3>

Recall that:

The linear equation with slope m and intercept c is given as follows.

y = mx + c

The formula for slope of line with points and can be expressed as

m = (y2 - y1)/(x2 - x1)

Given that

The orange line intersects y-axis at (0,-2), therefore the y-intercept is -2.

The orange line intersect the points that are (1,0) and (0, -2).

The slope of the line can be obtained as follows:

m = (-2-0)/(0-1)

= -2/-1

= 2

The slope of the line is m = 2.

Therefore, the orange line is y $\geq$ 2x -2

The blue line intersects y-axis at (0,-3), therefore the y-intercept is -3.

The blue line intersect the points that are (-4, -2) and (0, -3)

The slope of the line can be obtained as follows.

m = (-3-(-2))/(0-(-4))

= (-3 + 2)/4

= - (1/4)

The slope of the line is:
m = -(1/4)

The inequalities is x + 4y $\geq$ b passes through the point (0, -3)

(0) + 4 (-3) = b

-12 =b

Thus, -12 in is the number that completes the system. Hence, x + 4y $\geq$ -12
