The first step is to define the system of equations.
Take x and y as the cost of a small box and a large box respectively.
Solve the system.
A small box costs $4 and a large box costs $4 too.
Step-by-step explanation:
i. (2x+10)+(3x+5)+(2x+40) = 360
2x+3x+2x+10+5+40= 360
7x+55 =360
7x=360-55
<u>7x</u>= <u>3</u><u>05</u>
7. 7
x= 43.57=43.6
ii. 2x+10= 180
2x=180-10
<u>2</u><u>x</u>= <u>1</u><u>7</u><u>0</u>
2. 2
x=85
3x+5 =180
3x=180-5
<u>3</u><u>x</u>=<u>1</u><u>7</u><u>5</u>
3. 3
x= 57.5
2x+40=180
2x=180-40
<u>2x</u>=<u>140</u>
2. 2
x= 70
From the above 3x+5 which is 57.5 is the smallest interior angle of the triangle
iii. The largest interior angle of the triangle is 2x+10 which is 85
=x^2-8x+16-16
= (x-4) ^2-16
=[(x-4) -4][(x-4) +4]
=(x-8) x
Answer:
The number further left on a number line is the smaller number. For positive numbers, the number closest to zero is smaller. For negative numbers, the number closest to zero is larger. If a is less than b, and they are both positive, then a is closer to 0 than b. The opposite of a is also closer to zero than the opposite of b, so the opposite of a must be larger than the opposite of b.
