What the answers please

Step-by-step explanation:

let ,

pencil be x and ruler be y

so for Janet equation is

9x + 2y = £3.60 ← (eqⁿ 1)

for John

13x + 3y = £5.30 ← (eqⁿ 2)

now, multiply (eqⁿ 1) by 3 and (eqⁿ 2) by 2 so we got,

27x + 6y = 10.80 ← (eqⁿ 3)

and

26x + 6y = 10.60 ← (eqⁿ 4)

now, subtract (eqⁿ 4) from (eqⁿ 3) we got,

x = 0.2

since we got the value of x than let's find value of y

(eqⁿ 1)

→ 9(0.2) + 2y = 3.60

→ 1.8 + 2y = 3.60

→ 2y = 3.6 - 1.8 = 1.8

→ y = 1.8/2 = 0.9 ans.

therefore , x = £0.2 and y = £0.9

hence, value of pencil = £0.2 and ruler = £0.9.

hope this answer helps you dear...take care and may u have a great day ahead!

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
