Write 1/4 as a fraction with 8 as the denominator. Then add the fraction to 3/8. What is the sum? Write the fractions and the an
a_sh-v [17]

Answer:

2/8, 5/8

Step-by-step explanation:

\frac{1}{4}*\frac{2}{2} =\frac{2}{8} \\\\\frac{3}{8} +\frac{2}{8} =\frac{5}{8}

Multiplying by 2/2 is like multiplying by 1, so it doesn't affect the value.

To add fractions with the same denominator just add the numerator, the denominator stays the same.

true or false:the points (6,13),(21,33),(99,137)all lie on the-same line. the equation of the line is y=4/3x +5
Anit [1.1K]

The answer is true.

Step-by-step explanation:

To find the points all lie on the same line, we need to substitute the points in the equation of the line, to determine if the values on both sides of the equation are equal.

Substituting the point (6,13) in the equation of the line, we get,

\begin{aligned}y &=\frac{4}{3} x+5 \\13 &=\frac{4}{3}(6)+5 \\&=4(2)+5 \\&=8+5 \\13 &=13\end{aligned}

Thus, the values on both sides are equal. The point (6,13) lie on the same line.

Substituting the point (21,33) in the equation of the line, we get,

\begin{aligned}y &=\frac{4}{3} x+5 \\33 &=\frac{4}{3}(21)+5 \\&=4(7)+5 \\&=28+5 \\33 &=33\end{aligned}

Thus, the values on both sides are equal. The point (21,33) lie on the same line.

Substituting the point (99,137) in the equation of the line, we get,

\begin{aligned}y &=\frac{4}{3} x+5 \\137 &=\frac{4}{3}(99)+5 \\&=4(33)+5 \\&=132+5 \\137 &=137\end{aligned}

Thus, the values on both sides are equal. The point (99,137) lie on the same line.

Thus, all the three points lie on the same plane.

Hence, the answer is true.

Hi my lil bunny!

\boxed{ a^2 b^2 + -a^2 + -b^2 + 1 + 4ab}

Let's simplify step-by-step.

( a^2 - 1 ) ( b^2 -1) + 4ab

Distribute:

=( a^2) (b^2) + (a^2) (-1) + ( -1) (b^2) + (-1) (-1) + 4ab

= a^2 b^2 + -a^2 + -b^2 + 1 + 4ab
