How do i solve x/8=3/4

dusya [7]

Answer:

Quite simply. The answer is X=6

Since you have a full fraction, you can find a common denominator in both fractions and multiply. (The common denominator would be 8, so you would multiply 4 by 2 to get 8. Do the same thing to the top, do multiply 3 by 2 to get 6). Now the fraction is 6/8, and since it's equal to incomplete fraction, you know X is 6.

If you were to use the substitution method to solve the following system, choose the new equation after the expression equivalen

alexandr1967 [171]

The new equation after the expression equivalent to x from the first equation is substituted into the second equation is: $2(-4y-9)+5y=-6$

Step-by-step explanation:

We will solve the initial steps for substitution method for finding the correct answer

Given equations are:

$x+4y = -9\ \ \ \ Eqn1\\2x+5y=-6\ \ \ Eqn2$

From equation one

$x+4y = -9\\x+4y-4y = -9-4y\\x = -4y-9$

Putting x = -4y-9 in equation 2

$2(-4y-9)+5y=-6$

Hence,

The new equation after the expression equivalent to x from the first equation is substituted into the second equation is: $2(-4y-9)+5y=-6$

108 identical books have a mass of 30 kg. Find

Lynna [10]

Answer:

(i) 540kg

(ii) 5.56 (rounded off to 3 significant figures)

Step-by-step explanation:

$108 \div 30 = 3.6kg$

$(i)3.6 \times 150 = 540kg$

$(ii)3.6 \times x = 20$

$3.6x = 20$

$x = \frac{20}{3.6}$

$x = 5 \frac{5}{9}$
