Which of these best explains the next step to simplify this expression? 3y−45=35y−4 Question 22 options: Make the –4 exponent in
NISA [10]

The value of y from the give expression is 1

<h3>Expressions and equations</h3>

Give the following expression

\frac{3y^{-4}}{5} = \frac{3}{5y^{-4}}

Cross multiply the given expression

3y^{-4}\times 5y^{-4}= 5 \times 3\\15y^{-8}=15\\

Divide both sides by 15

y^{-8}=1\\\frac{1}{y^8} =1\\y^8=1\\y=1

Hence the value of y from the given expression is 1

A fruit stand has to decide what to charge for their produce. They decide to charge \$5.30$5.30dollar sign, 5, point, 30 for 111
MAVERICK [17]

Answer:

a + b = 5.30

a + b = 7

No

Step-by-step explanation:

Expressing the information as system of linear equation :

Let apples = a, oranges = b

If $5.30 is charged for one apple and one orange, then we have ;

a + b = 5.30 - - - (1)

If $14 is charged for 2 apples and 2 oranges, then we have ;

2a + 2b = 14 - - - - (2)

a + b = 7

Since both equations gives varying combined cost for equal amount of the fruit, then a unique cost cannot be obtained for each fruit from the systems of equation using simultaneous equation process.

From (1)

a = 5.30 - b

Put a = 5.30 - b in (2)

2(5.30 - b) + 2b = 14

10.6 - 2b + 2b = 14

10.6 = 14 - - - - - (variables cancels out).

Lines m and n are parallel. The measure of angle 6 is 55 114 57.6 3 What is the measure of angle 1? 1552​
Alex Ar [27]

Answer:

125 degree

Step-by-step explanation:

As m // n, so angle 2 and angle 6 is the same so angle 2 = 55 degree, then angle 1 + angle 2 = 180 degree, so angle 1 = 180 - 55 = 125 degree.
