A=1/4 and b=6 16a-4b a=1/4 and b=6 5b/32a= a=1/4 and b=6 12a+(b−a−4)=

Digiron [165]

Answers & Step-by-step explanation:

#1. Insert given values:

$16*\frac{1}{4} -4*6$

Simplify multiplication from left to right. Use the rule $\frac{a}{b}*c =\frac{ac}{b}$ :

$\frac{16}{4}-4*6\\\\ 4-4*6$

Simplify multiplication:

$4-24$

Simplify subtraction:

$-20\\\\16a-4b=-20$

#2. Insert given values:

$\frac{5*6}{32*\frac{1}{4} }$

Simplify multiplication:

$\frac{30}{32*\frac{1}{4} }$

Simplify multiplication. Use the rule $\frac{a}{b} *c=\frac{ac}{b}$ :

$\frac{30}{\frac{32}{4} }$

Simplify division:

$\frac{30}{8}$

Simplify fraction:

$\frac{15}{4} \\\\\frac{5b}{32a}=\frac{15}{4}$

#3. Insert given values:

$12*\frac{1}{4} +(6-\frac{1}{4} -4)$

Simplify subtraction within parentheses. Convert to fractions. Use the rule $a=\frac{a}{1}$ :

$\frac{6}{1} -\frac{1}{4} -\frac{4}{1}$

Make all denominators the same. Multiply top and bottom by 4 (only do this to the fractions with 1 as the denominator):

$\frac{24}{4}-\frac{1}{4}-\frac{16}{4}$

Simplify subtraction. Subtract the numerators. The denominator will stay the same:

$\frac{24}{4}-\frac{1}{4}-\frac{16}{4}=\frac{7}{4}$

Insert:

$12*\frac{1}{4} +\frac{7}{4}$

Simplify multiplication. Use the rule $\frac{a}{b} *c=\frac{ac}{b}$ :

$\frac{12}{4} =3$

Insert:

$3+\frac{7}{4}$

Simplify addition. Convert the whole number to a fraction. Use the rule $a=\frac{a}{1}$ :

$\frac{3}{1} +\frac{7}{4}$

Multiply top and bottom of the first term by 4:

$\frac{12}{4}+\frac{7}{4}=\frac{19}{4} \\\\12a+(b-a-4)=\frac{19}{4}$

:Done

If a plank which is 10 feet long is cut into

Firlakuza [10]

Answer:

If a plank which is 10 feet long is cut into two pieces and if one piece is x feet long,

Then the other piece will be (10 – x) feet long.

Here the value of the one piece is given as ‘x’ value

so the represent of the length of the other part will be (10 – x ) feet

Complete the equivalent equation for -7x-60 =x^2 +10x

alex41 [277]

Answer:

(x+12)(x+5)

Step-by-step explanation:

Formula use: a²+bx+c

Make one side equal to zero:

Original:

-7x-60 =x² +10x

New:

x² + 17x + 60

Multiply A with C

New:

(1)x x 60 = 60

Find factors of 60 that when added, equal to 17.

New:

10 × 6, 60 × 1, 20 × 3, 5 × 12, 4 × 15

5 times 12 equal 60, but when added equal to 17.

Replace the 17 with 5 and 12

New:

x² + 5x + 12x + 60

Break them off into two equations

New:

x² + 5x l 12x + 60

Divide each equation into it's simpilest form. Make sure the numbers in the ( ) are the same.

New:

x(x + 5) l +12(x+5)

Answer: (x+12)(x+5)
