There are 520'pages in the whole book because if you divide 390 by 3 you get 130 and if you multiply that by 4 you get 520, hope this helps! Please give brainiest answer and say thanks.
He spent $9.50 in total. To find this answer, you write the equation 2(9.95) + 3(1.20). You would distribute getting 5.90 + 3.60= $9.50.
Answer:
70 m^2
Step-by-step explanation:
The key shows that each square side on the grid measures 2 m. The base of the triangle measures 7 grid square sides, so it measures 14 m. The height of the triangle measures 5 grid square sides, so it measures 10 m.
area of triangle = bh/2
area = (14 m)(10 m)/2
area = 140 m^2/2
area = 70 m^2
Answer:
T = 9
Step-by-step explanation:
SAMDEB
1. Subtract 7 from both sides. 6T + 7 - 7 = 61 - 7
2. 6T = 54
3. Divide both sides by 6, to isolate T. 6T ÷ 6 = 54 ÷ 6
4. Therefore, T = 9
To solve add the ratio together and you get 10. 25/10 = 2.5
Now 2*2.5: 3*2.5: 5*2.5
= 5 : 7.5 : 12.5
