I can’t figure out the solution I think it is y < -10

Olenka [21]

Hey there!

With negatives ( $-$ ) you have to switch your symbol to the other way
$\bold{\frac{y}{-2}\leq5}$
Firstly, substitute the $\bold{y\ value }$ as an invisible 1
So, now we have to flip the equation around
$\bold{\frac{-1}{2}y\leq5}$
We have to $\bold{multiply}$ by $\bold{-2}$ on each of your sides
$\bold{-2\times\frac{-1}{2}\leq-2\times5}$
$\bold{Cancel \ out:2\times\frac{-1}{2}y \ because \ it \ equal \ 1}$
$\bold{Keep: -2\times5 \ because \ it \ helps \ us \ find \ our \ answer}$
$\bold{-2\times5=-10}$
$\boxed{\boxed{\bold{Answer:y\geq-10}}}\checkmark$

Good luck on your assignment and enjoy your day!

1. Pia printed two maps of a walking trail. The length of the trail on the first map is 8 cm. The length of the trail on the sec

Alex

Answer:

Step-by-step explanation:

b) 1- scale factor from the first map to the second map:

$\frac{8}{6}$ = 1.33

2- landmark on the first map is a triangle with side lengths of 3 mm, 4 mm, and 5 mm.

Side lengths of the landmark on the second map

Divide the length by scale factor:

side lengths of 3 mm: $\frac{3}{1.33}$ = 2.25 mm

side lengths of 4 mm: $\frac{4}{1.33}$ = 3.007 mm

side lengths of 5 mm: $\frac{5}{1.33}$ = 3.75 mm

Is 10/3 equivalent to 70/21

slava [35]

Yes because if you divide both, the numerator and denominator, by 7 it would simplify to 10/3, so they are equivalent.

An expression is shown below. What is the value of the expression?

dsp73

Answer:

Step-by-step explanation:

First you need to set up the equation 2/3+1/4/1/2, and we know that there is a stratgey for dividing fractions as well. But first, we need to find the least common fator for 2/3 and 1/4 which is twelve which would be 8/12+3/12 which is 11/12 and 11/12 dividing by 1/2 is 22/12 since all you need to do is do the keep change flip method which would give you an answer of 1 10/12 or 1 5/6
