Answer:
x=4.5 y=18.75
Step-by-step explanation:
solve using pythagorean theorem :
hypothenus²=opposite²+adjacent²
for y:
y²=15²+11.25²
y²=225+126.5625
y²=351.5625
y=18.75
for x:
7.5²=6²+x²
x²=7.5²-6²
x²= 56.25-36
x²=20.25
x=4.5
Answer:
it's geometric
Step-by-step explanation:
geometric equations change by a rate witch means you multiply to get to the next number in the sequence
arithmetic you add to get to the next number in the sequence
Answer:
$1.73
Step-by-step explanation:
$7.89-$6.16=$1.73
Answer:
Equation 1: 14t + 61s = 150
Equation 2: 14t + 25s = 78
Use Elimination (x)
(-1) (14t + 25s) = (78) (-1)
-14t - 25s = -78
14t + 61s = 150
+ -14t - 25s = -78
--------------------------
36s = 72
s = 2
Salad costs $2
Then find t
14t + 61(2) = 150
14t + 122 = 150
14t = 28
t = 2
Sandwich costs $2
