72° + (7x + 24) = 180
7x + (72 + 24) = 180
7x = 180 - 96
7x = 84 divide both sides by 7
x = 12

E. 7 * 391 = 2,100 + 630 + 7
Answers
Answer:
The answer is B
Step-by-step explanation:
The Distributive Property be used to find 7 x 391; 7 x 391 = (7 x 300) + (7x 90) + (7 x 1). Therefore, option D is the correct answer.
What is distributive property of multiplication over addition?Suppose a, b and c are three numbers. Then we have:
a(b + c) = a x b + a x c
(a(b+c) means a multiplied to (b+c). The sign of multiplication is usually hidden when using symbols and both quantities which are in multiplication are written together without space)
Also This property is known by distributive law and applies to subtraction also.
The Distributive Property be used to find 7 x 391;
7 x 391 = (7 x 300) + (7x 90) + (7 x 1)
Therefore, option D is the correct answer.

1. José tiene en su bolsillo un grupo de monedas de 5 y 10 centavos, y hay once
monedas más de 5¢ que las de 10€. Si el total es un dólar.
halla la cantidad de monedas de cada tipo.
Answers
Answer:
Hay 14 monedas de 5 centavos y 3 monedas de 10 centavos.
Step-by-step explanation:
Llamemos "c" a las monedas de 5 centavos y "d" a las monedas de 10 centavos.
Hay once monedas más de 5¢ que las de 10¢. La expresión matemática para ello es:
c = d + 11 [1]
El total es 1 dolar. La expresión matemática para ello es:
0,05c + 0,10d = 1 [2]
Si reemplazamos [1] en [2],
0,05(d + 11) + 0,10d = 1
0,05d + 0,55 + 0,10d = 1
0,15d = 0,45
d = 3
Si reemplazamos d = 3 en 1,
c = d + 11 = 3 + 11 = 14
If R is the midpoint of QS, find QS. QR=2x+16 RS=5x-17
Answers
Answer:
QS = 76
Step-by-step explanation:
Given R is the midpoint of QS, it means the distance from R to each endpoint is equal, that is:
QR = RS
We are given
QR = 2x + 16
RS = 5x - 17
Equating:
2x + 16 = 5x - 17
Subtracting 5x:
2x - 5x + 16 = -17
Simplifying:
-3x +16 = -17
Subtracting 16:
-3x = - 16 -17 = -33
Dividing by -3:
x = 11
Let's find
QR = 2x + 16 = 22 + 16 = 38
The length of QS is double this value: QS = 2*38 = 76
QS = 76

What is the value of x?
98°
Answers
Answer:
x = 139
Step-by-step explanation:
Isosceles triangle.
Let the equal angles = y
y + y + 98 = 180 {Sum of all the angles of triangles}
2y + 98 = 180
2y = 180 - 98
2y = 82
y = 82/2
y = 41
x = 41 + 98 { exterior angles equals the sum of interior opposite angles}
x = 139

Classify each of the following statements as true or false where a and b are whole numbers.
a. If GCD(a,b)= 1, then a and b cannot both be even.
b. If GCD(a,b) = 2, then both a and b are even.
c. If a and b are even, then GCD(a,b) = 2.
Answers
b. Is true because a GCD of 2 means that 2 is a factor in both a and b which means that they are both even.
c. is false because even numbers can have a greater factor shared than 2 like how 4 and 8 have a GCD of 4

Last year at a certain high school, 12 students sought the nomination for president of the student body. In how many ways could the voters (student body) rank their first 5 choices
Answers
Answer:
95,040 ways
Step-by-step explanation:
The first position has 12 choices
The second has 11 choices (since first is filled)
The third has 10 choices
The fourth has 9 choices
The fifth has 8 choices
So the number of ways they can make the ranking will be;
12 * 11 * 10 * 9 * 8 = 95,040 ways
The number of ways could the voters (student body) rank their first 5 choices is 792 ways.
Calculation of the number of ways:Since Last year at a certain high school, 12 students sought the nomination for president of the student body.
So, here
we use the combination here
[tex]= 12!\div 5!7!\\\\= 12\times 11\times 10\times 9\times 8\times 7!\div 5!7!\\\\= 12\times 11\times 10\times 9\times 8\div 5\times 4\times 3\times 2[/tex]

Find the values of x and y.
Answers
Answer: y = 129, x = 51
Step-by-step explanation:
angles 129 and y are corresponding, so they are equal to each other
y and x are supplementary
so, y + x = 180
x = 180 - y = 180 - 129 = 51
Answer:
I belive y has to be at least 133 because it's just a little bit longer than the 229 one.
And x is most likely to be 125 because if you line up 129 with x, x is should be a little smaller so x should be 125
Calculate the dot product of x = (1, −2, 0, 4) is in double-struck R4 and y = (1, 2, 3, 4) is in double-struck R4.

Step-by-step explanation:
The computation of the dot product is shown below:
Given that
x = (1, −2, 0, 4)
y = (1, 2, 3, 4)
Based on the above information
The dot product is
= (1) (1) + (-2) (2) + (0) (3) + (4) (4)
