Answer:
x = -2
Step-by-step explanation:
-9x + 1 = -x + 17
To solve this equation
Note if there is more than one variable like x, y, or z
Also note the power of the variables, for example, x^2 or y^3
In this equation, there is only one variable which is x and it's also in the power of 1 ie x
Step 1 : rearrange according to like terms
-9x + x = 17 - 1
( don't forget that the sign always change on crossing an equals to, either + to - or - to +
-9x + x (also means 9 - 1 but only carries a negative sign)
= - 8x = 16
Dividing both sides by -8 to get the value of x
-8x / 8 = 16 /- 8
x = 16/ -8
x = -2
Answer:
Jenna spent 7 hours babysitting.
Step-by-step explanation:
With the information provided, you can say that Jenna's total earnings are equal to the amount she earned cleaning her neighbor's basement plus the result of multiplying the charge per hour for babysitting for the number f hours, which is:
e=20+5x, where:
e represents the total earnings
x is the number of hours
Now, you can replace e with 55 that is the toal amount she earned and solve for x:
55=20+5x
55-20=5x
35=5x
x=35/5
x=7
According to this, the answer is that Jenna spent 7 hours babysitting.
<span>This equation have one solution.
</span><span>
5(2x – 3) = 5
2x - 3 = 5/5
2x - 3 = 1
2x = 1 + 3
2x = 4
x = 4/2
x = 2

The correct answer is B 26!/21! turned this in already and gotten a 100. Hoped this helped ya.
Answer:
317.6 feet
Step-by-step explanation:
the length of the diagonal can be determined using Pythagoras theorem
The Pythagoras theorem : a² + b² = c²
where a = length
b = base
c = hypotenuse
280² + 150²
= 78,400 + 22,500
= 100,900
take the square root of 100,900
= 317.648 feet
the tenth is the first number after the decimal place. To convert to the nearest tenth, look at the number after the tenth (the hundredth). If the number is greater or equal to 5, add 1 to the tenth figure. If this is not the case, add zero
317.6 to the nearest tenth
