From pt 1 to pt 2 there is a three unit change, from pt 2 to pt 3 there is a 3 unit change, from 3 to 4 there is a 5 unit change, and from 4 to 1 there is a 3 unit change. Add those together 3+3+3+5= 14 units is perimeter
To find area: look at image. answer is 30 units
Answer:
Step-by-step explanation:
Given:
Required
Multiply
The above can be written as
Split the above expression
Collect like terms
Apply first law on indices
Hence, is equivalent to
¹¹/48 of the full cup
Step-by-step explanation:
We add the two fraction first to determine the total ratio
¹/4 + ²/3 = ¹¹/12
She uses ¼ cup grape juice for ¹¹/12 cup full of diluted grape juice
Therefore;
¼ : ¹¹/12
How How much grape juice does Sarah use for each full cup of water, i.e ¹²/12
? (x) : ¹²/12
We cross multiply the ratios;
¹²/12 * ¼ = ¹¹/12 * x
³/12 = ¹¹/12 x
³/12 * ¹²/11 = x
¹¹/48 = x
Answer
z= 14
Step-by-step explanation:
4( 2z-3) -5(z-6) =3 *20
8z-12-5z+30=60
3z+18=60
3z=60-18
3z=42
z= 14
-3/4(x+2)=6
-3/4 is turned into a decimal, -0.75
-0.75(x+2)=6 distribute -0.75 to x and 2 (multiply)
-0.75x-1.5=6 add -1.5 under 6
-0.75x=7.5 divide -0.75 on both sides
-0.75x/-0.75 = 7.5/0.75
x=10
