Answer:
A = 29
Step-by-step explanation:
a triangle is equal to 180 so the bottom triangle you add 34 + 26 = 60 --> 180-60 = 120 ---> the triangle on top is 120 + 31 = 151 -----> 180-151 = 29

<h3>I'm solving it using substitution method:-</h3>
<h3>7x+2y=3 {given}</h3>
<h3>=>7x=3-2y</h3>
<h3>=>x=(3-2y)/7-------(1)</h3>
<h3>x-3y=30 {given}</h3>
<h3>=>x=30+3y</h3>
<h3>=>(3-2y)/7=30+3y {putting the value of x from eqn 1}</h3>
<h3>=>3-2y=210+21y</h3>
<h3>=>3-210=21y+2y</h3>
<h3>=>-207=23y</h3>
<h3>=>y= -207/23= -9</h3>
<h3>putting the value of y on eqn(1):-</h3>
<h3>x=(3-2y)/7</h3>
<h3>x=>(3-2(-9))/7=(3+18)/7=21/7=3</h3>
<h2>Hence, x=3, y= -9</h2>

Answer: 10:10
Step-by-step explanation:
68.80 because 7 is greater than 5
Answer:
The answer is $8.00.
Step-by-step explanation:
First, you have to find how much for each app so you have to divide by 3 :
3 apps = $2.40
1 app = $2.40 ÷ 3
1 app = $0.80
Next, you have to multiply it by 10 :
1 app = $0.80
10 apps = $0.80 × 10
10 apps = $8.00
