Mathematics
1 answer:
Ket [755]3 years ago
0 0

Answer:

3 3/4    OR   3.75

Step-by-step explanation:

If Mai walked 1/8 of a total 30 miles then you multiply both of them in fraction form, so you find the one eighth,

\frac{30}{1} * \frac{1}{8}     now we multiply the numerators and denominators

30 * 1 = 30              1 * 8 = 8

30/8             now we divide

3 3/4      or 3.75

ULT ma<br> 4. Write an expression, then evaluate.<br> a. 1/4of the sum of 18 and 6
OlgaM077 [116]

Answer: Required expression: \dfrac14\times(18+16)

Result: \dfrac{17}{2}

Step-by-step explanation:

Given phrase:  " \dfrac14\text{ of the sum of } 18\text{ and }6. "

Required expression: \dfrac14\times(18+16)    ['+' used to express sum, 'x' used in place of 'of']

Since 18+16 = 34

Then,

\dfrac14\times(18+16)=\dfrac14\times34  \\\\=\dfrac{1}{2}\times17\ \ \text{[Divide numerator and denominator by 2]}\\\\=\dfrac{17}{2}

Hence,     \dfrac14\times(18+16)=\dfrac{17}{2}.

V125BC [204]

<u>Let's solve this problem step by step</u>

<u />2x+3=4(x-6)    |    Given Equation

2x+3=4x-24     |    Distributive Property of Multiplication over subtraction

3=2x-24             |    Subtraction Property of Equality

27=2x                   |     Subtraction Property of Equality

\frac{27}{2}=x                     |     Division Property of Equality

<em>Definition of each property</em>:

  • <u><em>Distributive Property of Multiplication over subtraction</em></u><em>: it says that the product of a number and the difference of two other numbers is equal to the difference between the products of the distributed number.</em>
  • <u><em>Subtraction Property of Equality</em></u>:<em> if the same value is subtracted from two equal sides, the differences remain the same</em>
  • <u><em>Division Property of Equality</em></u><em>: if the same value is divided from two equal sides, the equation remains the same</em>

<em />

Hope that helps!

baherus [9]

Answer:

f(7)=58

b(-2)-a(12)=-188

Step-by-step explanation:

f(7)=(7)^2+9

49+9

f(7)= 58

b(-2)-a(12)=8(-2)-14-13(12)-2
