Hello!
We can go through each answer to verify whether each is equivalent to 8 : 6.
4 : 3 is equivalent to 8 : 6 because reducing the ratio 8 : 6 by a factor of 2 yields 4 : 3.
6 : 8 is not equivalent to 8 : 6 because the ratio is reversed.
16 : 12 is equivalent to 8 : 6 because the ratio is increased by a factor of 2.
10 : 8 is not equivalent to 8 : 6. We can verify this by checking whether each term was scaled equally:
10 ÷ 8 = 1.25
8 ÷ 6 = 1.33. Therefore, they are unequal.
7 : 5 is not equal to 8 : 6 for the same reason.
The only correct choices are:
4 : 3 and 16 : 12.
Answer:
3x=21
X=7
Step-by-step explanation:
Answer:
13.
Let us say
first angle be = 4x -10
second angle = x
now add them to 90 as complementary angles add up to 90
4x - 10 + x = 90
5x - 10 = 90
5x = 90+10
5x = 100
x = 100/5
x = 20
the first angle = 4x -10
= 4(20) -10
= 80 -10
= 70
the second angle = x
= 20
the angles are 70 and 20
Answer:
FALSE
Step-by-step explanation:
If p could equal 10, 20, 30 or 40 lets put each of them in the expression 7.4p<=74
1. 7.4 times 10 equals 74 so that work✅
2. 7.4 times 20 equals 148 so that does not work X
3. 7.4 times 30 equals 222 so that does not work X
4. 7.4 times 40 equals 296 so that does not work X
