Answer:
B
Step-by-step explanation:
From the given information:
Sienna has $8 denotes the unit blocks of x tiles. So, she saved $3 per week.
This implies that:
8x + 3(1) = 8x + 3
Also,
If Jacob as well had $6 which implies 6x unit block of tiles while he saved $4;
i.e.
6(x) + 4(1) = 6x + 4
So;
the model that can determine when Sienna will have the same amount as Jacob is:
8x + 3 = 6x + 4
4/11•7/1=28/11
Answer: 28/11 or 2 6/11
Answer:
f(x)=2(x-3) yup that's the answer
Answer:
4cm^2
Step-by-step explanation:
First we need to find the length of the height of the triangle using Pythagoras:
a^2+b^2=c^2 (Substitute in what we have)
a^2+3√2(^2)=2√5(^2) = a^2 + 18 = 20 -> 20-18=2 √2=BD
Now we can find the area:
AD+DC= 3√2 + √2 = 4√2 x √2 = 8/2 = 4
18 / 1 = x / 15......18 miles to 1 gallon = x miles to 15 gallon
cross multiply
(1)(x) = (18)(15)
x = 270 miles
