Answer:
The length of x is 4
Step-by-step explanation:
The scale factor is Large/small where 10/8 which is DF/AC.
THE SCALE factor is 5/4.
To find the length of X is in AB we use the scale factor 5/4 and the corresponding DE.
5/4 = DE/AB
5/4 = 5/X
X = 4
To find Y in EF will use the corresponding BC which is 6.
5/4 = EF/BC
5/4 = Y/6
Y= 7.5
info: use CORRESPONDING ABC AND DEF .
I learned this trick months ago.
Step-by-step explanation:
ratios are kinda like fractions
5/15 could be used as 2/6 if you criss cross it 5x6=30 and 15x2=30
Here are a list of fractions (just turn them into ratios) that would work
1/3 1:3
2/6 2:6
3/9 3:9
4/12 4:12
5/15 5:15
6/18 6:18
7/21 7:21
8/24 8:24
9/27 9:27
10/30 10:30
Answer:
3yz^3 + 1
Step-by-step explanation:
t(5x^3yz^2) = 15x^3y^2z^5 + 5x^3yz^2
t = [5x^3yz^2(3yz^3 + 1)]/5x^3yz^2
t = 3yz^3 + 1
Answer:
8-4
Step-by-step explanation:
Since x equal 1 for now. The first step you do is x plus 3 which equal 4. Then do 2 time 4 which is 8. 8 equal the x so the answer is 8-4
Answer:
Step-by-step explanation:
150 kilometers
60 kph
tank is 20 liters
6 km/l
