Answer:
Kyle invested 5,800 at 10% and 5,400 at 7%.
Step-by-step explanation:
Let x be the amount Kyle invests in the 10% account.
0.1x + 0.07(11200 - x) = 958
0.1x + 784 - 0.07x = 958
0.03x = 174
x = 5800
Answer:
In Step 4, the inequality sign should be flipped.
Step-by-step explanation:
Whenever you multiply or divide both sides of an inequality by a negative number, you need to flip the inequality sign. So, in Step 4, when you divide both sides by -10, the sign should be flipped.
The final answer should be:
Answer:
1) x - 4 is greater than or equal to 18
x is greater than or equal to 22
2) 12 + x is less then or equal to 17
x is less the or equal to 5
3) 23 is less than x + 16
7 is less than x
4) -6 + x is greater than or equal to -7
x is greater than or equal to -1

Answer:
21 coins of ₹2
Step-by-step explanation:
Let x represent the number of ₹2 coins, and y the number of ₹5 coins. Then the total value of the coins is ...
2x +5y = 77
and the relationship between numbers of coins is ...
x = 3y
Substituting for x, we have ...
2(3y) +5y = 77
y = 77/11 = 7 . . . . simplify, divide by the coefficient of y
x = 3(7) = 21 . . . . find x from the second equation
Ram has 21 of the ₹2 coins.
