Answer:

$20

Step-by-step explanation:

let 1 meter of sulu = s, lusia has m dollar

7s = m + 1 => m = 7s - 1

5s = m - 5

5s = 7s - 1 - 5

2s = 6

s = 3

m = 7s - 1 = 21 - 1 = 20

Un radar de l'armée américaine réussit à détecter tout ce qui se trouve à un rayon représenté
WARRIOR [948]

Répondre:

r <27

Explication étape par étape:

Compte tenu de l'inégalité 5r + 9> 10r - 126

Nous devons trouver l'ensemble de solutions

5r + 9> 10r - 126

Ajouter 126 des deux côtés

5r + 9 + 126> 10r - 126 + 126

5r + 135> 10r

5r-10r> -135

-5r> -135

Divisez les deux côtés par -5 (notez que le signe changera)

-5r / -6 <-135 / -5

r <27

Par conséquent, les ensembles de solutions sont des valeurs inférieures à 27

How to find the area of a triangle with a base of 32ft
Sergeu [11.5K]
Well to find the area of any figure you must first have knowledge on the formula. The formula for a triangle is 1/2 x b x h. Since you have the base 32, multiply that by 1/2 which will give you 16. Then you have to multiply 16 by the height. I'm not sure what the height is because you never gave me one but hopefully this helped! God bless :)
