Answer:
3
1
2
Step-by-step explanation:
Math simplification
Just do 7/4 and cross multiply with 1/2
Change you’ll receive is = 0.09
you can only buy 11 because if you divide 20/11 it will give you 1.81 and if you multiply 11x 1.81 it will give you 19.91 which is close to $20 & that’s the most you can buy .
Answer:
25 ft
Step-by-step explanation:
The 2 triangles are similar hence the ratios of corresponding sides are equal, that is
= 
= 5
multiply both sides by 5
x = 5 × 5 = 25
The height of the tree is 25 ft
Answer:
I am not sure how your teacher wanted you to estimate the answer but I solved it for you. Hopefully this helps.
Step-by-step explanation:
7x-y=7
x+2y=6
14x-2y=14
x+2y=6
add both equations
15x=20
x=20/15
x=4/3
x+2y=6
4/3+2y=6
2y=6-4/3
2y=18/3 -4/3
2y=14/3
divide both sides by 2
y= 14/3 divided by 2
y=14/3(1/2)
y=14/6
2y=
