#1 4/5x + 2/3x = 1 -4/15
22/15x = 11/15
x = 1/2
and can u explain what u mean by #2 and #3??
Answer:
hypotenuse = squareroot of 61 cm. which is approximately 7.81025 cm
Step-by-step explanation:
5 squared + 6 squared = hypotenuse squared
square root of (5 squared + 6 squared)= hypotenuse
Answer:
26. <u>c. 6 cm</u>
27. <u>c. 70 cm³</u>
Step-by-step explanation:
<u>Question 26</u>
- Volume = Length × Width × Height
- 360 = 10 × 6 × Width
- Width = 6 cm
- <u>c. 6 cm</u>
<u></u>
<u>Question 27</u>
- Volume = Length × Width × Height
- Volume = 7 × 5 × 2
- Volume = 70 cm³
- <u>c. 70 cm³</u>

<u>Question 28 (not entirely visible)</u>
Answer:
x=-3, y=-19
Step-by-step explanation:
we can solve by substitution.
y = 2x-1 we can derive from the second equation.
plugging it into the first equation, 2x -3(2x-1) = 15.
simplying, 2x-6x+3 = 15 --> -4x+3 = 15, -4x = 12, x = -3.
now we know x, so we can solve for y by plugging it into one of the equations. --> -3*-6+y = -1
simplify, 18+y = -1 --> y = -19.
