Answer:
Jeremy have 19 dollars left.
Step-by-step explanation:
He withdrew $4.50 3 times, so he withdrew $4.50x3 = $13.50 in total
$32.50 — $13.50 = $19
Jeremy had 19 dollars left on his account.
Step-by-step explanation:
a) 3x + 5y = 8
4x - 3y = 1
• using the elimination method:
3x + 5y = 8 (×4)
4x -3y = 1 (×3)
12x + 20y = 32
12x -9y = 3
subract 12x from both equation:
20y - - 9y= 32 -3
20y +9y = 29
29y= 29
y= 29/29
y= 1
- substituting y= 1 in :
4x - 3y= 1
4x - 3(1) = 1
4x -3 = 1
4x = 1 + 3
x = 4/4
x= 1
b) 6p+ 4q = 20
5p - 2q = 6
• using the elimination method:
6p + 4q = 20
5p - 2q = 6 (×2)
6p + 4q = 20
10p - 4q = 12
add 4q + -4q to eliminate q.
6p+ 10p = 20+12
16p = 32
p = 32/ 16
p = 2
- subtituting p = 2 in :
5p - 2q = 6
5(2) -2q =6
10 -2q = 6
-2q = 6 - 10
q = -4 / -2
q = 2
hope this helps you,

Answer:
i believe it is 21.285 or 21.29 since yo multiply 5.50 times 3.87 to get 21.285
Step-by-step explanation:
Answer: 1.67
Step-by-step explanation:
Z = ( x - mean) / standard deviation
Z = (97-75) / 12
= 20 / 12 = 1.67
