Answer:
20 = 4n
n = 5
Step-by-step explanation:
Given that :
Number of gifts Keiko wrapped = 20
Let number of gifts wrapped by Henry = n
Keiko wrapped 4 times as many gifts as Henry
Hence,
20 = 4n
The equation that relates the number of gifts wrapped is :
20 = 4n
To obtain n ;
Divide both sides by 4 to isolate n
20/ 4 = 4n / 4
5 = n
Hence,
n = 5
Answer:
If my thinking is right she should weigh about 18 pounds or so.
Step-by-step explanation:
17% of 174 is 29
17% of 108 is 18
Use the Point-Slope formula: y - y1 = m(x - x1)
-1 = m, x1 = 0, y1 = 5 y - 5 = -1(x - 0)
Distribute the (-1): y - 5 = -x
Add 5 to both sides: y = -x + 5
Answer:
(11,-23)
Step-by-step explanation:
3a+b=10 equation 1
-4a-2b=2 equation 2
using equation 1 we have
b = 10-3a equation 3
using equation 2 we have
-4a-2(10-3a)=2
-4a-20+6a=2
2a-20=2
2a=22
a=22/2
a=11
so using equation 3
we have
b = 10-3(11)= 10-33
b=-23
finally the answer is
(11,-23)
12 because u add and then times
