5/8x - 11/2 = 3/4 <br> what does the x equal ?
Verizon [17]

Answer:

x=10

Step-by-step explanation:

5/8x - 11/2 = 3/4

Multiply each side by 8 to clear the fractions

8(5/8x - 11/2 = 3/4)

5x - 44 = 6

Add 44 to each side

5x-44+4= 6+4

5x= 50

Divide by 5

5x/5 = 50/5

x =10

Pls solve question 4b. Verrry urgent . Ok tyy
kodGreya [7K]

Answer:

y = 3\left(x-\dfrac{3}{2}\right)^2+\dfrac{41}{4}

Step-by-step explanation:

Given equation:

y = 3x^2 - 9x + 17

Factor out 3 from the first 2 terms:

y = 3(x^2 - 3x) + 17

Divide the coefficient of x by 2 and square it:  (-3 ÷ 2)² = 9/4

Add this inside the parentheses and subtract the distributed value of it outside the parentheses:

y = 3\left(x^2 - 3x+\dfrac{9}{4}\right) + 17-\dfrac{27}{4}

Factor the parentheses and combine the constants:

y = 3\left(x-\dfrac{3}{2}\right)^2+\dfrac{41}{4}

Answer:

A- 16 songs a day

B- 32 songs in the weekend

Step-by-step explanation:

A- if she songs "jingle bells" 5 times, the sings"silver bells" twice as many times, that would just be like multiplying  5 x 2, which equals 10, then add the 5 times she sings jingle bells, that would be 15. then she sings "silent night" one time which adds on to the other songs to get 16 songs a day

B- the weekend has 2 days in it so you would just multiply 16 x 2 which gives you 32
