Bracelet cost = b
Necklace cost = n
15b + 8n = 500
19b + 24n = 980
Elimination method x -3
-45b - 24n = -1500
19b + 24n = 980
-26b = -520
b = $20 bracelets
Plug back in
19(20) + 24n = 980
380 + 24n = 980
24n = 600
n = $25 necklaces
Check:
15(20)+ 8(25)= 500
300 + 200 = 500
500 = 500 :)
Answer:
7500 kg
Step-by-step explanation:
t = tonnes
Let a/b and c/d represent two rational numbers. This means a, b, c,and d are INTEGERS , and b and d are not 0. The product of the numbers is ac/bd , where bd is not 0. Both ac and bd are INTEGERS , and bd is not 0. Because ac/bd is the ratio of two INTEGERS, the product is a rational number.
The answer is -8/2 or choice B.
Answer:
1.function 1 has a greater rate of change than function 2
3. Function 1 has a greater y-intercept than function 2
Step-by-step explanation:
Using the table we can find the slope using
m = (y2-y1)/ (x2-x1)
m = (29-5)/ (8-0)
= 24/8
= 3
The rate of change for the table is 3
The y intercept is (0,5)
Using the graph (0,-1) and (2,0)
m = (y2-y1)/ (x2-x1)
m = (0--1)/ (2-0)
= (0+1)/2
= 1/2
The y intercept is (0,-1)
Since 3>1/2 , function 1 has a greater rate of change than function 2
Since 5>-1, function 1 has a greater y-intercept than function 2
