What is the value of x?<br><br> Enter your answer in the box.<br><br> x =

Nikitich [7]

You are given that all three sides are equal. You also know that all three angles are also equal. Therefore since all three angles are equal and every triangle has 180 degrees, each angle is 180/3 = 60

7x - 3 = 60 Add three to both sides

7x - 3 + 3 = 60 + 3 Combine

7x = 63 Divide by 7

7x/7 = 63/7

x = 9 And that's your answer.

Last Tuesday was silly hat day at Toby's school. 74 students wore a silly hat and 666 students did not. What percentage of the s

valina [46]

Answer:

10%

Step-by-step explanation:

The total population of students will be equal to the sum of both those who wore the silly hat and those who didn't hence

Total students= 74+666=740

Number of students who wore silly hat is given as 74 hence when expressed as a percentage of the total students' population we get that

percentage of the students wore a silly hat= $\frac {74\times 100}{740}=10\%$

Therefore, 10% of students wore a silly hat last Tuesday

Jose asks his friends to guess the higher of two grades he received on his math tests. He gives them two hints. The difference o

Answer : 96

x – y = 16 --------> equation 1

$\frac{1}{8} x +\frac{1}{2} y = 52$

x is the higher grade and y is the lower grade

We solve the first equation for y

x - y = 16

-y = 16 -x ( divide each term by -1)

y = -16 + x

Now substitute y in second equation

$\frac{1}{8} x +\frac{1}{2} ( -16 + x ) = 52$

$\frac{1}{8} x - 8 + \frac{1}{2} x = 52$

$\frac{1}{8} x + \frac{1}{2} x - 8 = 52$

Take common denominator to combine fractions

$\frac{1}{8} x + \frac{4}{8} x -8 = 52$

$\frac{5}{8} x - 8 = 52$

Add 8 on both sides

$\frac{5}{8} x = 60$

Multiply both sides by $\frac{8}{5}$

x = 96

We know x is the higher grade

96 is the higher grade of Jose’s two tests.

Can someone help pls

Answer:

Slope = 4/3

Step-by-step explanation:

Formula for slope-intercept form: y=mx + b

Given: 3y - 4x = -6

Add -4x to the right hand side to isolate out 3y (y).

It should look like this: 3y = 4x -6

Now divide both sides by 3.

You should get: y = 4/3x -2

Since it's asking for slope, your slope is 4/3.
