Answer:
7:11
Step-by-step explanation:
You place the numbers in the order given.
70:110
Then reduce it to the lowest term. In this case by 10.
70 ÷10=7
110÷10=11Therefore, the answe is
7:11
Plug 4x=9 in for y:
10x=18-2(4x+9)
10x=18-8x-18
10x=-8x
18x=0
x=0
now plug 0 in for x:
y=4(0)+9
y=9
to check, plug x and y back into one of the equations to make sure they are right:
10(0)=18-2(9)
0=18-2*9
0=18-18
0=0
Answer:
Angle CDE equals 155 degrees :D
Step-by-step explanation:
parallel lines
since the left angle is 57, angle BAE is also 57
180-57=123
right angle=90
115+90+123+57=385
540-385=155
thus, angle CDE equals 155 degrees
Answer:
5 cases
10 additional units
Step-by-step explanation:
Given that :
Total number of units needed = 60 units
Total number of units per case = 14
Hence, the total number of cases required will be :
Number of units needed / number of units per case
Number of cases required = 60 / 14 = 4.285 (this means that 5 cases are required as 4 cases won't be up to 60 units)
With 5 cases, we have exceeded the required units needed :
Additional units will be : (14 * 5) - 60
Additional units = 70 - 60 = 10 units
