C=2 times j
c=2j
o=j-6
c+j+o=58
subsitte j-6 for o and 2j for c
2j+j+j-6=58
4j-6=58
add 6 to both sides
4j=64
divide both sides by 4
j=16
sub back
c=2j
c=2(16)
c=32
o=j-6
o=16-6
o=10
curtis=32
olivia=10
jonathan=16
equations are
c+j+o=58
c=2j
o=j-6
Answer:
65 = 6x + 7
6x = 58
x = 9.6666666...
65 + y + 9 = 180
y = 106
Step-by-step explanation:
Answer:
-1 Degree C
Step-by-step explanation:
When its talking about average temperature, its talking about the mean. To calculate mean, you add all the numbers and divide it by how many numbers are there.
(-8) + (-1) + 2 + 4 + (-2) = -5
mean = -5/5
-1 degree C
X=5
90°-50°=40°
5x+15=40°
5x=25°
x=5
Answer:
The length of AC = 25
Step-by-step explanation:
Triangle ABD is a right triangle and can use the Pythagorean theorem which is 
+ 
= 
one leg is BD = a = 12
hypothenuse is BA = c = 15
other leg is AD = b, which we need to find
+ =
= -
= 
- 
= 225 - 144
= 81
b = leg AD = 9
The length of AC = AD + 16 (given in picture) = 9 + 16 = 25
I hope this helps
