Answer:
³y+7-6x=16
Step-by-step explanation:
this is an example of a 3 evaluating expression equation. *I think*
Set up the equation by writing the number of students in the ratio as a fraction:
3/4= (245-x)/x Cross multiply:
3x= 4(245-x) Multiply on right:
3x= 980-4x Add 4x on both sides:
7x= 980 Divide both sides by 7:
x= 140 this is how many girls there are. And:
245-140= 105= boys
X = 8
Y = 2 Your welcomeeeeee
Answer:
the twins will always have the same age
Step-by-step explanation:
the equation for jasmine's age is 2(3x+6), while the equation for james's age is 3(2x+4)
2(3x+6) = 2*3x + 2*6 = 6x + 12
3(2x+4) = 3*2x + 3*4 = 6x + 12
since both have the same equation, both will be the same age when you plug in the same x value
