y=2x-3
y=x+2 system of equations
Answer:
x = 5
y = 7
Step-by-step explanation:
Since they are both equal to y, we can set them equal to each other.
2x - 3 = x + 2
Combine like terms and isolate the x.
x = 5
Plug in the x to either equation to get the value of y.
y = (5) + 2
y = 7

What is the value of (a+b) in the system of equations below?
6(a + b) + 2z = -8
a+b+z = 2
Selett one:
A. 3
O B.-4
O C. - 3
O D.-1
Answer:
C
Step-by-step explanation:
6(a+b) + 2z = -8 ; divide by 2
3(a+b) + z = -4
a+b+z = 2; subtract z from both sides
a+b = 2-z; substitute a+b into equation 3(a+b) +z = -4
3(2-z) +z = -4; distribute
6 - 3z+ z= -4 ; subtract 6 on both sides
-3z + z = -4 -6 ; combine like terms
-2z = -10; divide both sides by -2
z= 5
3(a+b) +z = -4; substitute z by 5
3(a+b) +5 = -4; subtract 5 from both sides
3( a+b) = -4 -5; combine like terms
3(a+b) = -9; divide both sides by 3
(a+b) = -3

Answer:
True
Step-by-step explanation:
it is 3/5. Than 6/10 is equal to 3/5. Than 9/15 is equal to 3/5.
Answer: True
Step-by-step explanation:
That is true because let's take the first point for example.
3 cups of almonds for 5 cups of oats.
3/5 of 5 is 3
So that's correct.
If you still aren't sure you should try that with a different point. Hmm how about :
9 cups of almonds for 15 cups of oats
3/5 of 15 = 45/5 = 9
That's correct as well.
Hope these helps!

Answer:
Isabelle sold 60% of the corn on Saturday
Step-by-step explanation:
In order to calculate the percentage of the corn that Isabelle sold we first need to divide the number of corn that she sold by the total number of corn that she had initially.
150 / 250 = 0.6
Now we simply need to multiply this decimal value by 100. This will give us the percentage of corn sold as a percentage value.
0.60 * 100 = 60%
Therefore, we can see that Isabelle sold 60% of the corn on Saturday

If 8 engines consume 12000 kgs. of coal when each running 10
hours per day, how much coal is required for 7 engines out
which 5 are running 12 hours a day and the rest 6 hours a day?
Answer:
11200 for 7 engines for a total of 80 hours
Step-by-step explanation:
You have 8 engines burning 12000 .for 10 hours.
Divide 10 hours into 12000=1200 PER hour.
1200 ÷8 engines = 140 per hour per engine.
140 × # of hours (12)=1680 for 12 hours per engine.
# of engines × 1680 for 12 hour/per engine
5×1680 = 8400 of fuel for 12 hours/5 engine
Then you have 2 that runs 10 hours
2 × 140 per hour per engine =280 × 10 =2800 for 2 engines for 10 hours
8400. + 2800= 11200 of fuel for 6 engines
