Answer:
I got 109
Step-by-step explanation:
f(x)=5(x+4)-6 x=19
f(19)=5(19+4)-6
*Add 19 + 4 because it is in ()* f(19)=5(23)-6
*Multiply because it is the first in the order of operations* f(19)=115-6
*Now just subtract* f(19)= 109
Answer:
9)x=135º
10)x=2 23º
11)x=2 122º
Step-by-step explanation:
15x-7=19x-15
-4x=-8
4x=8
x=2
54x+14=43x+36
11x=22
x=2
Answer:
<h2>y=7x-47</h2>
Step-by-step explanation:
so umm this is the answer
Perimeter = 2(length + width)
P = 2(L+w)
We are told the length is 3 times the width...
L = 3w
64 = 2(3w + w)
64 = 2(4w)
64 = 8w
8 = w
L = 3w = 3(8) = 24 cm
Length is 24 cm
width is 8 cm
1. 46 ft 2. 21 yd 3. 16 ft 4. 52 cm 5. 30 in 6. 12 miles 7. 63 mm 8. 75 in 9. 55 cm
