Answer:
I) 23
K) 96
J) 77
Step-by-step explanation:
All angles of a triangle equal up to 180
6x+4x-3+x+7=180
11x+4=180
11x=176
x=16
4x-7=29 < do you understand how to set that up? Now, the goal is to “get x by itself.”
4x-7=29< now add the 7 to the 29. When you cross an equals sign you change the (+/-) sign of the number you’re moving.
4x= 36< now you will just divide by 4 on both sides. This will give you x by itself on the left side of the equals sign.
x=36/4 which is 9
X=9 :))
So all u have to do is just add $1.28 and $0.54
Answer:
Step-by-step explanation:
62 degrees Fahrenheit
Step-by-step explanation:
The number of snowy tree cricket chirps per minute is 148 less than 4 times the outside temperature in degrees Fahrenheit.
Let x = number of chirps
f = temp in Fahrenheit
x = 4f -148
Now let x = 100
100 = 4f-148
Add 148 to each side
100+148 = 4f-148+148
248 = 4f
Divide each side by 4
248/4 = 4f/4
62=f
5 quarters =1.25$
15$÷1.25$=12
then 15$ in quaters would weigh 12 ounces
