For the first table, e is elephant and b is beavers. We are basing the number of beavers on the number of elephants, therefore, elephants is just e, while beavers is e = 3b. For the second table, children's tickets are c while adults are a. We are basing the cost of the child ticket on the adult ticket, so the adult ticket is just a, while the child's ticket is a - 6.
Answer:
Maggie
Step-by-step explanation:
1/4 of a mile = approx. 2.5 KM in 78 seconds (1.3 mins)
2/3 of a mile = approx. 2.6KM in 174 seconds (2.9 mins)
so Maggie is going faster
Answer:
$210
Step-by-step explanation:
Given data
time = 6 weeks
initial amount= $90
saving per week = $25
Hence the expression for the total savings after the 6 weeks is given as
y= mx+c
where
m= $25
x= 6 weeks
c= $90
substitute
y=25*6+90
y= 150+60
y= $210
Hence the total amount after 6 weeks is $210
Answer:
x = 5 and y = 13
Step-by-step explanation:
<u>Points to remember</u>
The ratio of of corresponding sides of similar triangles are equal.
From the figure we can see two similar triangle
<u>To find the value of x</u>
x/(x + 15) = 12/48
x/(x + 15) = 1/4
4 * x = x + 15
4x - x = 15
3x = 15
x = 15/3 = 5
<u>To find the value of y</u>
y/(y + 39) = 12/48 = 1/4
4y = y + 39
3y = 39
y = 39/3 = 13
Therefore x = 5 and y = 13
Answer:
part A
y = 2x -1
the slope is 2/1 means it will be up 2 right 1 or down 2 left 1 the slope is positive
the y-int is -1
y = 4x -5
the slope is 4/1 means it will be up 4 right 1 or down 4 left 1 the slope is positive
the y-int is -5
part B
the solution to this is (2,3)
