Answer:
x=25/23
Step-by-step explanation:
Let's solve your equation step-by-step.
−23x+37=12
Step 1: Subtract 37 from both sides.
−23x+37−37=12−37
−23x=−25
Step 2: Divide both sides by -23.
x=25/23
Step-by-step explanation:
<u>Given:</u>
- Total distance is 500 km
- Total time is 5 1/2 h
- The distance travelled at 100 km/h is x
- The distance travelled at 80 km/h is y
<u>We know that:</u>
<u>Considering all the info we can make below chart:</u>
Nikolas' car trip
<u> | at 100 km/h | at 80 km/h | Total |</u>
<u>Distance | x | y | 500 km |</u>
<u>Time | x/100 | y/80 | 5 1/2 h |</u>
X+4multiply by y=7
Moved these terms to left-7
It becomes X+4 multiple y-7=0
X+4 multiple y-7=0
Answer:
yard
Step-by-step explanation:
Length of string Mrs. Ruiz has = yard
Mrs. Ruiz needs to hang 3 banners using the string.
Having known that each banner uses same length of string to be hung we can divide total length of sting into 3 equal parts.
So, we can divide yard by 3 as
⇒
Changing the division sing to multiplication by taking reciprocal of divisor.
⇒
We can now multiply numerators and denominators.
⇒ yard
∴ Mrs. Ruiz must used yard of string for each banner.
A whole number doesnt have a fraction in it or a decimal.
