12.99+ 3.75x= total. therefore, 12.99+3.75(4)= 27.99
Answer:
x = 16
m<Y = 34°
Step-by-step explanation:
∆XYZ is an isosceles ∆. An isosceles ∆ has two equal sides, as well as the bases of the isosceles triangle are congruent. In this case, therefore:
<X = <Z
(6x - 23)° = (4x + 9)
Solve for x
6x - 23 = 4x + 9
Collect like terms
6x - 4x = 23 + 9
2x = 32
Divide both sides by 2
x = 16
m<Y = 180° - (m<X + m<Z) (sum of ∆)
m<Y = 180 - ((6x - 23) + (4x + 9))
Plug in the value of x
m<Y = 180 - ((6(16) - 23) + (4(16) + 9))
m<Y = 180 - (73 + 73)
m<Y = 34°
Answer:
Ok that's not it
x=-1 then y=4
x=0 then y= 6
x=1 then y = 8
x=2 then y= 10
x=3 then y= 12
Step-by-step explanation:
when y=2x+6
you have to plug what it says x is in each of the equations.
For the first one it says x=-1
you then plug that in and you get y=2(-1)+6
then you go through PEMDAS and first you get y=-2+6
-2+6 = 4
therefore y=4
and you just go through the rest wiht that
Step-by-step explanation:
The answer is 2 19/50.
First of all you have to convert the mixed numbers into improper fractions. So, 1 2/5 is equal to 7/5 and 1 7/10 is equal to 17/10. Next you multiply the denominators by the denominators and multiply the numerator by the numerator. 7 times 17 is 119 and 5 times 10 is 50. So the fraction is 119/50. You convert the improper fraction into a mixed number, which is 2 19/50.
Okay so lets look at this.
So we have 5/5 girls.
2/5 of them are playing softball. An equal number of girls signed up to play pitcher, infield, and outfield. This means that each one is 1/3.
So out of 2/5 of the girls, there is 1/3 of the 2/5 that signed up to play outfield.
The answer can be solved with multiplication of fractions.
2/5 * 1/3 is 2/15. So 2/15 of the girls in the school signed up to play outfield.
Answer: 2/15 or 0.133
