Answer:
x=31°
Step-by-step explanation:
Ok,
We know the sum of the angles in a triangle add up to 180°.
So,
2x+63+(2x-7)=180
2x+63+2x-7=180
Add like terms
4x+56=180
4x=124
x=31°
Hope this helps!
Answer:
m<ABC = 40
m<FEC = 90
because the triangle is isoscles
Answer:
-175
Step-by-step explanation:
Subtract (10 divided into fifths) from (20 divided into half)
= (20 divided into half) - (10 divided into fifths)
= (20 / 2) - (10 / 5)
If you need to solve this expression expression:
= 10 - 2
= 8
I hope this helps you
In order to solve this equation you could use guess and check with multiple choice, or you can set up a system of equations.
First we must define our variables:
x=price of taco
y=price of burrito
Michael bought 4 tacos (4x) and (+) and Burrito (y) for $9.50 (=9.5)
4x+y=9.50
Noah bought two tacos (2x) and (+) three burritos (3y) for (=) $11 (11)
2x+3y=11
To solve this system of equations you can easily see substitution as the easiest method. For substitution we must isolate one variable:
4x+y=9.50
y=-4x+9.5
We can now replace the y in the other equation:
2x+3(-4x+9.5)=11
Then solve this equation to get the price of a taco (x)
2x-12x+28.5=11
-10x=-17.5
x=1.75
The price of a taco would be $1.75
