Answer:

Step-by-step explanation:

[tex]5x - 26 =x +50[/tex]

Collect like terms and simplify

[tex]5x-x =50+26\\\\4x = 76[/tex]

Divide both sides of the equation by 4

[tex]\frac{4x}{4} = \frac{76}{4}[/tex]

Simplify

[tex]x=19[/tex]

Answer:

Step-by-step explanation:

The given equation is linear with two variables that will have zero solutions.

A system of equations, also known as an equation system or a set of simultaneous equations, is a finite set of equations for which common solutions are sought.

Given equation is x + 2y = 8. The equation is a linear equation with two variables. If the equation will have another equation then the solution will have two values for two variables.

If there is only one equation with two variables we will not get any solution we need one more same equation. The equation will have zero solution.

Therefore, the given equation is linear with two variables that will have zero solutions.

The equivalent expression is: -2x + 10. therefore the correct option is C.

Those expressions who might look different but their simplified forms are same expressions are called equivalent expressions.

To derive equivalent expressions of some expression, we can either make it look more complex or simple. Usually, we simplify it.

From the distributive property;

-2(x - 5)

Then, multiply -2 and -5

-2 * x = -2x

-2 * -5 = 10

because two negatives make a positive

Therefore the answer would be -2x+10.

Hence,The equivalent expression is: -2x + 10. therefore the correct option is C.

Answer:

y=150x+200

Step-by-step explanation:

Given that:

Week : ____ 0___ 1 ___ 2 ____3 _____4

Balance : __200_350 _ 500 _ 650 ___800

Amount had in savings account = $200 before starting the job

x = number of weeks spent working

y = account balance

Slope intercept formula :

y = mx + c

C = intercept ; value of y when x = 0 = 200

m = slope or gradient = change in salary per month (350 - 200 = 500 - 350 = 650 - 500 = 800 - 650 = 150

Hence,

y = 150x + 200

Answer:

10

Step-by-step explanation:

When we subtract a negative number, it's basically a double negative, kind of like how we don't use those in English. We want to turn that into a positive, and double negatives are positive.

So, instead of 7-(-3), we get 7+3, or 10

Answer:

10

Step-by-step explanation:

[remember: (+)(+) is (+) itself , (+)(-) is (-) , (-)(-) is (+) ]

(+7)-(-3)

⇒ +7+3

⇒ 10

Answer:

3 cm : 1 cm

Step-by-step explanation:

1. 60 : 20

2. divide 10 on both sides = 6 : 2

3. divide by 2 on both sides = 3 : 1

4. 3 cm : 1 cm

I'm so sorry, I just read the ratio is 60 cm to 20 M

So edit:

convert both into a unit, we'll take m.

1 cm = 100 m

so 60 x 100 = 60000 m

= 60000 m : 20 m

= divide by 20 in both sides...

= 3000 m : 1 m

v = 22.5 miles/hour

Step-by-step explanation:

It is given that,

The speed of Penguins is 33 ft/s.

We need to convert the speed to miles per hour.

We know that, 1 mile = 5280 feet

Speed,

[tex]v=33\ \dfrac{ft}{s}\\\\=33\times \dfrac{\dfrac{1}{5280}\ \text{miles}}{\dfrac{1}{3600}\ \text{hour}}\\\\=22.5\ \text{miles/hour}[/tex]

So, the speed of the Penguins is 22.5 miles/hour.
