Answer:
y= -1/2
x=3/2
Step-by-step explanation:
first isolate x
2x+4y=1
2x=1-4y
x=(1-4y)/2
subsitute it in the second equation

Answer:
A) Isaac should get £ 10.75 in change.
B) The price of the e-scooter in the sale is £ 366.3.
Step-by-step explanation:
A) Given that Isaac buys 17 anti-pollution masks for £ 5.25 each, and he pays with five £ 20 notes, to determine how much change Isaac should get, the following calculation must be performed:
(20 x 5) - (17 x 5.25) = X
100 - 89.25 = X
10.75 = X
So Isaac should get £ 10.75 in change.
B) Given that the normal price of an e-scooter is £ 370 and, in a sale, there is 1 off the normal price of the e-scooter, to determine the price of the e-scooter in the sale the following calculation must be performed:
370 - (370 x 0.01) = X
370 - 3.7 = X
366.3 = X
Thus, the price of the e-scooter in the sale is £ 366.3.
Step-by-step explanation:
Olivia is correct. Each O is opposite of the angle θ, and each A is adjacent.

Step-by-step explanation:
Use proportions to solve this exercise
Work with two triangles ΔRSQ and ΔRTS
Side RQ = 14
Side RS = q
Side RS = q
Side RT = 4
14/q = q/4 Solve for q
56 = q²
q = √56
Find prime factors of 56
56 2
28 2
14 2
7 7
1 Then 56 = (2²)(2)(7)
= √(2²)(2)(7)
= 2 √ 14
